Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that, if not conflicted, the various features of the embodiments of the present application may be combined with each other within the scope of protection of the present application. Additionally, while functional block divisions are performed in apparatus schematics, with logical sequences shown in flowcharts, in some cases, steps shown or described may be performed in sequences other than block divisions in apparatus or flowcharts. In addition, the words "first", "second", "third", and the like used herein do not limit the data and execution order, but merely distinguish the same items or similar items having substantially the same functions and actions.

Before the present application is explained in detail, terms and expressions referred to in the embodiments of the present application are explained, and the terms and expressions referred to in the embodiments of the present application are applicable to the following explanations:

(1) electrochromic is a phenomenon in which optical properties (reflectivity, transmittance, absorption, etc.) of a material undergo a stable and reversible color change under the action of an applied electric field, and is visually represented as a reversible change in color and transparency. Materials having electrochromic properties are referred to as electrochromic materials, and devices made with electrochromic materials are referred to as electrochromic devices. The electrochromic material has bistable performance, and the electrochromic display device made of the electrochromic material does not need a backlight lamp, and does not consume power as long as the display content is not changed after a static image is displayed, thereby achieving the purpose of energy conservation. Compared with other displays, the electrochromic device has the advantages of no visual blind angle, high contrast, low manufacturing cost, wide working temperature range, low driving voltage, rich colors and the like, and has great application prospects in the fields of instrument display, outdoor advertising, static display and the like.

The memory, including solid-state memory, will carry on the real-time record or upgrade in the fixed storage area that the job will be present state or trouble dispose inside, the host computer can visit these information through the port appointed in advance. If desired, the user or administrator can access the ports via the host to view the information. In some memory product designs, a plurality of items of information which are important or common are displayed visually by arranging an indicator light or an LED screen on the surface of a shell.

Currently, it is inconvenient to view or manage due to lack of visual display of memory status or failures; or even if such functions and components are present, their operation needs to be in a memory power-on state.

On one hand, if the storage has no visual display of the state or the fault, although the user or the administrator can call the corresponding port to obtain the information through the host, the method is not only inconvenient and inefficient, but also prone to errors (such as large-scale data centers, tens of even millions of disks in cloud computing centers, and many steps are required to find and confirm a certain fault disk).

On the other hand, in the design of some memory products, one or more important or commonly used items of information are visually displayed by arranging an indicator light or an LED screen on the surface of the shell; however, once powered down, this information is likewise not visible. In some situations, such as power-off maintenance of a data center, return to a factory due to a fault, etc., a user or a worker may want to be able to screen and judge the state or fault of a memory in a power-off state, but the prior art still cannot meet the requirement.

Based on this, the embodiment of the application provides a storage device, which improves the state detection efficiency of the storage device.

The technical scheme of the application is specifically described in the following with the attached drawings of the specification:

referring to fig. 1, fig. 1 is a schematic structural diagram of a memory device according to an embodiment of the present disclosure;

as shown in fig. 1, the storage device 100 includes: a main control module 110, a color change control module 120, and an electrochromic device 130, wherein,

the main control module 110 is connected to the color change control module 120, and configured to monitor status information occurring in the storage device 100, so as to send a control signal to the color change control module 120, so as to wake up the color change control module 120; wherein the status information includes but is not limited to: fault information, usage status information, for example: available space information, available capacity information, health index information, recent use time information, and bad block number information.

The color-changing control module 120 is connected to the main control module 110 and the electrochromic device 130, and is configured to receive the control signal sent by the main control module 110, generate a pulse signal, and send the pulse signal to the electrochromic device 130, so as to control the energization voltage and/or the energization time of the electrochromic device 130;

the electrochromic device 130 is disposed on the housing of the storage device 100, connected to the color-change control module 120, and configured to change a display color of the electrochromic device according to the power-on voltage and/or power-on time, so as to adjust the display color of the housing of the storage device 100.

Referring to fig. 2 again, fig. 2 is a schematic structural diagram of a memory device according to an embodiment of the present disclosure;

as shown in fig. 2, the storage device 100 is in communication connection with a host in a wired or wireless manner to implement data interaction, and the storage device 100 may be a storage device such as a Hard Disk Drive (HDD), a Solid State Drive (SSD), a mobile Hard Disk, a fixed Hard Disk, and the like, where the storage device is provided with a housing.

Specifically, the storage device 100 includes: the main control module 110, the color-changing control module 120, the electrochromic device 130, the dynamic storage module 140, and the plurality of flash memories 150.

The main control module 110 is a main controller or an SSD controller, and includes a processor 111, a host interface controller 112, a cache controller 113, a flash memory controller 114, a cache unit 115, and a data codec unit 116.

Specifically, the processor 111 is respectively connected to the host interface controller 112, the cache controller 113 and the flash memory controller 114, wherein the processor 111, the host interface controller 112, the cache controller 113 and the flash memory controller 114 may be connected by a bus or other methods, and the processor is configured to run nonvolatile software programs, instructions and modules to implement data processing or command processing of the main control module 110.

In the embodiment of the present application, when the storage device 100 runs, the master control module 110 monitors the running states of all components including the master control module 110, for example: the operating status of one or more of the processor 111, the host interface controller 112, the cache controller 113, the flash memory controller 114, the cache unit, the data codec unit 116, and the flash memory 150 in the main control module 110. When a change or a change in one or more states associated with the color-change control module 120 is found, i.e. a predefined fault or state occurs, the processor 111 sends a hardware reset signal to the color-change control unit 121 of the color-change control module 120 to wake up the color-change control unit 121 of the color-change control module 120, for example: and the one-chip microcomputer sends the state information or the fault information corresponding to the fault to the color change control unit 121, so that the color change control unit 121 enters a working mode after being awakened, receives the state information or the fault information sent by the processor 111, and sends a pulse signal to the signal conversion unit 122 according to the state information or the fault information, so as to control the energization voltage and/or the energization time of the transparent conductive layer of the electrochromic device 130, so that the color change of the outer shell portion or the whole outer shell portion of the storage device occurs.

Specifically, the host interface controller 112 is connected to the processor 111, the cache controller 113 and the flash memory controller 114, and is configured to control an interface interfacing with the host, where the interface is configured to receive data sent by the host, or receive data sent by the processor 111, and implement data transmission between the host and the processor 111, and the interface includes an SATA-2 interface, an SATA-3 interface, an SAS interface, an MSATA interface, a PCI-E interface, an NGFF interface, a CFast interface, an SFF-8639 interface, and an interface of m.2nvme/SATA protocol.

Specifically, the cache controller 113 is connected to the processor 111, the cache unit 115, and the dynamic storage module 140, and is configured to control data in the cache unit 115, for example: read data or write data sent by the host.

Specifically, the flash memory controller 114 is connected to the processor 111, the cache controller 113, the data codec unit 116, and the flash memories 150, and is configured to access the flash memories 150 at the back end and manage various parameters and data I/O of the flash memories 150; or, an interface and a protocol for providing access, implementing a corresponding SAS/SATA target protocol end or NVMe protocol end, acquiring an I/O instruction sent by a host, decoding and generating an internal private data result to wait for execution; or, the core processing responsible for Flash Translation Layer (FTL). The flash memory controller 114 uses flash memory commands conforming to the standards of flash memory ONFI and Toggle to manage the reading and writing of data from the cache to the flash memory. The flash memory controller is coupled to and communicates with the flash memory, and from a single flash memory perspective, a Die/LUN is the basic unit of flash memory command execution.

Specifically, the cache unit 115 is mainly used for caching the read/write command sent by the host and the read data or the write data acquired from the flash memory 150 according to the read/write command sent by the host.

Specifically, the data encoding/decoding unit 116 includes an ECC module for performing ECC check. It can be understood that, since the error rate of flash memory is inherent, for the correctness of data, ECC check protection should be added to the original data during the data writing operation, which is an encoding process. When reading data, it also needs to detect and correct errors by decoding, and if the number of bits of errors exceeds the ECC correction capability, the data will be uploaded to the host in a form of "uncorrectable". Here, the ECC encoding and decoding process is performed by the data codec unit 116. The ECC algorithm in SSD is mainly BCH and LDPC, wherein LDPC is becoming mainstream gradually.

The color-changing control module 120 is connected to the processor 111 and the electrochromic device 130, and is configured to receive a control signal sent by the processor 111 to control a display color of the electrochromic device 130.

The color change control module 120 includes: a color-changing control unit 121 and a signal conversion unit 122, wherein the color-changing control module 121 is connected to the signal conversion unit 122, and the color-changing control unit 121 is configured to receive the control signal sent by the processor 111 to generate a pulse signal, and send the pulse signal to the signal conversion unit 122, so that the signal conversion unit 122 controls the display color of the electrochromic device 130 according to the pulse signal.

Specifically, the color-changing control unit 121 is connected to the processor 111 of the main control module 110, and is configured to receive a control signal sent by the processor 111 of the main control module 110 and generate a pulse signal;

specifically, the signal conversion unit 122 is connected to the color-changing control unit 121 and the electrochromic device 130, and is configured to receive the pulse signal sent by the color-changing control unit 121, and control the power-on voltage and/or power-on time of the electrochromic device 130 according to the pulse signal, so as to control the display color of the electrochromic device 130. The electrochromic device comprises a transparent conducting layer, and the signal conversion unit is used for controlling the electrifying voltage and/or the electrifying time of the transparent conducting layer so as to enable the electrochromic device to generate color change.

In this embodiment of the application, the color change control unit 121 includes a single chip, for example: the AT89S52 single chip microcomputer is configured to receive a control signal sent by the processor 111 of the main control module 110 to output a Pulse signal, where the Pulse signal includes a Pulse Width Modulation (PWM) signal, and the signal conversion unit 122 includes a digital-to-analog converter or an analog filter, and the digital-to-analog converter or the analog filter converts the PWM signal output by the single chip microcomputer into a continuous voltage value.

In the embodiment of the present application, after the color change control unit 121, for example, a single chip microcomputer, executes the corresponding external color display control operation, the single chip microcomputer enters the power down mode or the sleep mode again by setting the register, and since the power consumption of the single chip microcomputer is reduced to 2mA when the single chip microcomputer enters the sleep mode, the power consumption of the single chip microcomputer can be reduced to below 0.1 μ a when the single chip microcomputer enters the power down mode, and the power consumption is different by tens of thousands of times. It is to be understood that, since the outer color control does not work frequently, it is preferable to control the color-change control unit to enter the power-down mode after adjusting the display color of the housing of the storage device. In the embodiment of the present application, the color-changing control unit 121 includes, but is not limited to, a single chip, a microprocessor, a central processing unit, and other processing units with data processing capability. Wherein, singlechip includes 51 singlechips.

The electrochromic device 130 is disposed on the housing of the storage device, and may be the entire housing or a part of the housing, and the electrochromic device 130 may change its color according to the state information or the failure information of the current state of the operation of the storage device 100, so as to change the color of the housing of the storage device 100.

It will be appreciated that since the electrochromic device 130 is reversibly color-changing, when one or more states associated with the color-change control module 120 are reversible, i.e., a reversible failure, such as: the working temperature is too high, the available capacity is too low, and the like, along with the operation of the storage device, the possible fault state can be recovered to the normal state, at the moment, the shell color change of the storage device can also be reversely changed, and the processing process is similar to the processing process of the forward change. Specifically, the main control module, for example: the main controller or the SSD controller sends a hardware reset signal to wake up the color change control unit 121 of the color change control module 120, and sends state information or fault information corresponding to one or more reversely changed states to the color change control unit 121; the color-changing control unit 121 is awakened and then enters a normal operation mode, receives the fault information or the state information sent by the processor 111, determines the external color control according to the fault information or the state information, and outputs a pulse signal, and the signal conversion unit 122, for example: a digital-to-analog converter (DAC) or an analog filter, according to the color change control unit 121, for example: the pulse width modulation output (PWM) of the single chip controls the energization voltage and energization time of the transparent conductive layer in the electrochromic device 130, so that the color of the case of the storage device changes. And after the single chip microcomputer executes the corresponding external color control operation, the single chip microcomputer enters the power-down mode again through the setting register.

It will be appreciated that if the above states do not reverse during operation of the memory device or after a restart, the color of the housing of the memory device will remain consistent depending on the characteristics of the electrochromic material.

It should be noted that there are other types of states of the memory device that cannot be self-inverted, such as the proportion of bad blocks exceeding a threshold value, the wear life reaching a dangerous period, and the like. At this moment, after the color of the shell corresponding to the state or the fault is changed, the self-inversion cannot be realized, and the self-inversion can be always kept even after the storage equipment is powered off, so that the classification, screening and other works of the storage can be realized by related personnel of a user or a manufacturer. It can be understood that, if the storage device with the irreversible failure is maintained or returned to the factory for maintenance, the corresponding failure problem is solved, and the shell color of the storage device can be reversely changed into the original normal color through an external circuit or an internal interface instruction of the storage device.

Specifically, please refer to fig. 3 again, fig. 3 is a schematic structural diagram of an electrochromic device according to an embodiment of the present disclosure;

as shown in fig. 3, the electrochromic device includes: transparent protective layer, transparent conducting layer, electrochromic layer, electrolyte layer, ion storage layer and base plate layer.

The transparent protective layer, namely the transparent insulating protective layer, is arranged on the uppermost layer or the outermost layer of the electrochromic device;

the substrate layer is arranged at the lowest layer or the lowest layer of the electrochromic device, and the substrate layer can be a colored material or a transparent material, but a black material or a nearly black material is not adopted in the aspect of enhancing the contrast.

The transparent conducting layers are arranged below the transparent protective layer and above the substrate layer, one electrochromic device comprises two transparent conducting layers, one transparent conducting layer is grounded, and each transparent conducting layer at least has two characteristics, namely, a good electronic conductor and high light transmittance. Two common types of transparent conductive glasses, fluorine (F) -doped tin oxide (SnO)₂) The transparent conducting layer used as the conducting glass is called FTO glass for short; tin doped indium oxide (In)₂O₃) The transparent conductive layer used as the conductive glass is called ITO glass for short;

and the electrochromic layer is arranged below the upper transparent conductive layer, wherein the electrochromic layer uses electrochromic materials such as transition metal oxides and organic conductive polymers. Under the action of an external electric field, charge transfer occurs, and the performance of the electrochromic device is mainly determined by the electrochromic layer.

The electrolyte layer is arranged in the middle of the electrochromic device and used for providing a transmission channel of ions for electrochromic effect, the complex of the polyethylene oxide and the alkali metal salt has good ion conduction characteristic, and the polymer electrolyte is an excellent ion transmission layer substance.

And the ion storage layer is arranged below the electrolyte layer and is used for storing and providing ions required by the electrochromic material. Releasing ions to be injected into the electrochromic layer under the action of an external electric field; when a reverse electric field is applied, ions released from the electrochromic layer are stored.

It can be understood that the electrochromic layer and the ion storage layer are subjected to opposite oxidation or reduction processes under the action of an electric field, namely, the ion storage layer is subjected to reduction reaction while the electrochromic layer is subjected to oxidation reaction, so that after the display color of the shell of the storage device is changed, the singlechip can be powered off, and the display color of the shell can still be maintained after the storage device is powered off.

The dynamic storage module 140 is used as a storage unit of the main control module 110, and is used for storing data of the main control module, or is used for loading programs and data for the processor 111 of the main control module 110 to directly run and operate. In the embodiment of the present application, the Dynamic Memory module 140 includes a Dynamic Random Access Memory (DRAM).

The Flash memory 150, which is a storage medium of the storage device 100 and is also called a Flash memory, or a Flash granule, is a type of storage device, is a nonvolatile memory, can store data for a long time without current supply, and has storage characteristics equivalent to a hard disk, so that the Flash memory 150 can be a basis of a storage medium of various portable digital devices.

In some embodiments, the host module further comprises a data converter (not shown) respectively connected to the processor and the flash controller, the data converter being configured to convert the binary data into hexadecimal data and the hexadecimal data into binary data. Specifically, when the flash memory controller writes data into the flash memory, the binary data to be written is converted into hexadecimal data by the data converter, and then written into the flash memory. When the flash memory controller reads data from the flash memory medium, hexadecimal data stored in the flash memory is converted into binary data by the data converter, and then the converted data is read from the binary data page register. The data converter may include, among other things, a binary data register and a hexadecimal data register. The binary data register may be used to store data converted from hexadecimal to binary, and the hexadecimal data register may be used to store data converted from binary to hexadecimal.

Referring to fig. 4 again, fig. 4 is a schematic flowchart of a control method of a storage device according to an embodiment of the present disclosure;

as shown in fig. 4, the method for controlling a storage device includes:

step S401: monitoring status information occurring in the storage device;

specifically, the storage device includes a main control module, and the main control module monitors the operating states of all components including the main control module, for example: the running state of one or more of the processor, the host interface controller, the cache controller, the flash memory controller, the cache unit, the data codec unit and the flash memory in the main control module, and the state information includes but is not limited to: fault information, usage status information, for example: available space information, available capacity information, health index information, last usage time information, bad block number information, for example: and if a certain component fails, sending a control signal to the color change control module according to the state information corresponding to the failure.

Step S402: and sending a control signal to the color change control module according to the state information so as to wake up the color change control module to enter a normal working mode, and further controlling the power-on voltage and/or power-on time of the electrochromic device so as to adjust the display color of the shell of the storage device.

Specifically, according to the state information, a control signal is sent to the color change control module to wake up the color change module to enter a normal working mode, and then the power-on voltage and/or power-on time of the electrochromic device is controlled to adjust the display color of the shell of the storage device.

For example: when one or more states related to the color-change control module are found to be changed or changed, that is, predefined state information occurs, the processor sends a hardware reset signal to the color-change control unit of the color-change control module to wake up the color-change control unit of the color-change control module, for example: and the singlechip is used for sending the state information or fault information corresponding to the fault to the color change control unit, enabling the color change control unit to enter a working mode after being awakened, receiving the state information or the fault information sent by the processor, and sending a pulse signal to the signal conversion unit according to the state information or the fault information so as to control the electrifying voltage and/or the electrifying time of the transparent conducting layer of the electrochromic device and enable the shell part or the whole part of the storage device to be subjected to color change.

In this embodiment of the application, the color-changing control module includes a color-changing control unit and a signal conversion unit, and sends a control signal to the color-changing control module according to the state information, including:

determining whether the state information belongs to predefined state information, wherein the state information includes but is not limited to: fault information, usage status information, for example: available space information, available capacity information, health index information, latest use time information and bad block number information;

Specifically, a first state information set is predefined, where the first state information set includes state information related to the electrochromic device, that is, any one of the state information included in the first state information set is used to cause the electrochromic device to change color. If the processor of the main control module judges whether certain state information belongs to predefined state information, namely, judges whether certain state information belongs to a first state information set, if so, the processor determines that the state information belongs to the predefined state information, the processor sends a control signal to a color change control unit of the color change control module, wherein the control signal comprises a hardware reset signal and a digital signal corresponding to the state information, the hardware reset signal is used for awakening the color change control unit in the color change control module, and the digital signal corresponding to the state information is used for enabling the color change control unit to output a calculation result according to a prefabricated program and sending the calculation result to a signal conversion unit, so that the signal conversion unit converts the calculation result into a voltage signal and applies the voltage signal to a transparent conducting layer of the electrochromic device to enable the electrochromic device to generate color change.

As shown in fig. 5, the overall flow of the control method of the storage device includes:

step S501: the master control module monitors that the storage equipment has state change;

specifically, the processor of the main control module monitors the operating states of all components of the storage device, for example: the running state of one or more of a processor, a host interface controller, a cache controller, a flash memory controller, a cache unit, a data coding and decoding unit and a flash memory in the main control module.

If a certain state change belongs to the predefined state information, step S502 is entered;

step S502: the main control module sends a hardware reset signal to the color change control module to wake up the color change control module to enter a normal working mode;

specifically, the processor of the main control module sends a hardware reset signal to the color change control unit of the color change control module to wake up the color change control unit and the signal conversion unit of the color change control module, so that the color change control module enters a normal working mode;

step S503: the master control module sends a digital signal corresponding to the state information to the color change control module;

specifically, the processor of the main control module sends a digital signal corresponding to the state information to the color change control unit of the color change control module, so that the color change control unit receives the digital signal corresponding to the state information.

Step S504: the color change control module outputs a calculation result based on a preset program according to the digital signal corresponding to the state information;

specifically, after the color change control module receives the digital signal corresponding to the state information, the digital signal corresponding to the state information is calculated based on a preset program according to the digital signal corresponding to the state information, so as to output a calculation result.

For example: the state change comprises fault information, if only one fault definition exists, a bit of

binary information

0 or 1 is used for indicating that the fault occurs, 0 is no fault, and otherwise, the fault occurs. When a fault occurs, 8 'b 00000001 (8 bits are filled), indicating that a fault occurs, and 8' b01111111 is output.

Step S505: the signal conversion unit converts the calculation result into a voltage signal and applies the voltage signal to the electrochromic device to enable the electrochromic device to generate color change;

specifically, the color change control unit sends the calculation result to the signal conversion unit, and the signal conversion unit, for example: digital-to-analog converters, which convert digital signals into voltage signals, such as: converted to a voltage of +5V and applied to the transparent conductive layer of the electrochromic device to cause the electrochromic device, and thus the housing of the memory device, to undergo a color change.

Step S506: a color change control unit of the color change control module enters a power-down mode;

specifically, after the shell of the storage device is subjected to color change, the color change control unit of the color change control module enters a power-down mode through the setting register, so that the electrochromic device still keeps displaying in a power-down state.

In an embodiment of the present application, by providing a method for controlling a storage device, the method is applied to the storage device of the above embodiment, and the method includes: monitoring fault information occurring in the storage device; and sending a control signal to the color change control module according to the state information so as to wake up the color change control module to enter a normal working mode, and further controlling the power-on voltage and/or power-on time of the electrochromic device so as to adjust the display color of the shell of the storage device.

The state change of the storage device is monitored to control the power-on voltage and/or power-on time of the electrochromic device so as to adjust the display color of the shell of the storage device, and the state detection efficiency of the storage device can be improved.

In an embodiment of the present application, the memory device comprises at least two electrochromic devices, each electrochromic device comprising: transparent protective layer, transparent conducting layer, electrochromic layer, electrolyte layer, ion storage layer and base plate layer, wherein, at least two electrochromic wares are the stack structure.

It will be appreciated that the colour appearance depends primarily on the choice of electrochromic material, and although multicolour variations can be achieved by controlling the voltage, and energisation time, the contrast is not strong and sometimes even very difficult to distinguish; some metal organic complexes, such as phthalocyanine and lutetium (Lu), can change the electrochromic range among red, green, blue and purple, but still have the problems of small multicolor change range and even low contrast among colors and difficult distinction.

At present, the problem of wide color switching is difficult to realize by using one electrochromic material, so that the storage device has more excellent color changing performance, such as higher color purity and wider color range, for example, three electrochromic devices which respectively correspond to three primary colors are used for superposition, and richer color expression is realized by using a multi-electrochromic device superposition mode and a multi-color superposition mode.

Specifically, referring to fig. 6 again, fig. 6 is a schematic diagram of a superimposed structure of an electrochromic device provided in the embodiment of the present application;
