As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
According to the invention, the central server is set up, and the sequence code configuration file is placed in the central server, so that in the mass production test process, a plurality of product test positions on a machine table have one sequence code configuration file at the same time, and only one sequence code configuration file can be accessed, and the sequence code configuration file of the central server is updated after the sequence code is written in the product, so that the problem of sequence code repetition is solved; and deleting the current first sequence code acquisition signal in the stack area, so that no repeated sequence code acquisition signal exists in the stack area.
Specific implementations of the present invention are described in detail below with reference to specific examples.
Example one
Referring to fig. 1, a method for generating a serial code of a memory chip according to a first embodiment of the present invention includes steps S01 to S03:
step S01, the central server obtains the sequence code obtaining signals transmitted from all the test bits, and stores all the sequence code obtaining signals in the stack area in sequence.
In the testing process of the memory chip, the automatic testing machine is responsible for controlling the testing of all the memory chips, sending a mass production signal to the testing computer, automatically detecting the signal by mass production software on the testing computer, controlling the testing bits to start firmware burning testing, writing sequence code information into the memory chips in the firmware burning process, and uniformly distributing sequence codes obtained by each testing bit by the central server; the central server communicates with the mass production software on each test computer through a network or a serial port, the firmware burning test is carried out to the sequence code writing process, sequence code acquisition signals are sent to the central server to acquire the sequence codes, then the central server monitors the sequence code acquisition signals sent by each test position and sequentially stores the sequence code acquisition signals into the stack area, and therefore the sequence code acquisition signals are sequentially stored into the stack area. The mass PRODUCTION software, also called a USB DISK mass PRODUCTION TOOL (PDT for short), writes corresponding data into the USB DISK, so that the computer can correctly identify the USB DISK, and the USB DISK has some special functions.
In step S02, the central server determines whether the current index value of the serial code configuration file is occupied.
Step S03, if yes, the central server obtains the latest sequence code generated by the sequence code configuration file, and returns the latest sequence code to the test bit corresponding to the first sequence code obtaining signal in the stack area, and meanwhile, the sequence code configuration file records the latest index value of the latest sequence code.
Specifically, the sequence code acquisition signal is used for inquiring the sequence code configuration file to try to acquire the current index value of the latest sequence code, and the current index value is returned to the test bit corresponding to the first sequence code acquisition signal in the stack area, and the latest index value of the latest sequence code is recorded, so that the situation that the sequence codes are acquired next time and overlapped does not occur is avoided.
In the method for generating the sequence code of the memory chip, the central server acquires the sequence code acquisition signals transmitted from all the test positions and stores all the sequence code acquisition signals in the stack area in sequence; then judging whether the current index value of the sequence code configuration file is occupied or not through the central server; if so, the central server acquires the latest sequence code generated by the sequence code configuration file, and returns the latest sequence code to the test bit corresponding to the first sequence code acquisition signal in the stack area, and meanwhile, the sequence code configuration file records the latest index value of the latest sequence code; by the method, in the mass production test process, a plurality of product test positions on the machine table have one sequence code configuration file at the same time, and the sequence code configuration file is updated after the latest sequence code is written into the product, so that the sequence code is increased progressively and is not repeated; the configuration file of the same sequence code can be continuously updated, a plurality of mass production software is not required to be divided, misoperation is reduced, unused fields which can be represented by the sequence code cannot be generated, the sequence code in the same batch is unique, the number of produced samples is more than 42 hundred million, and the requirement of large-batch products can be met.
Example two
In another embodiment of the present invention, referring to fig. 1, after the step of the central server determining whether the current index value of the sequence code configuration file is occupied, the method further includes the following steps:
if not, the step that the central server judges whether the current index value of the sequence code configuration file is occupied is executed in a traversing way. When the central server judges that the current index value of the sequence code configuration file is not occupied, the central server indicates that the current sequence code configuration file does not generate the sequence code corresponding to the current index value, and the latest sequence code can be directly configured, so that the sequence code is ensured to be increased progressively without being repeated.
EXAMPLE III
In an embodiment of the present invention, referring to fig. 2, the method for recording the latest index value of the latest serial code by the serial code profile includes steps S031:
step S031, obtain the index start value, index end value, and index marker of the latest sequence code.
The method for recording the latest index value of the latest serial code by the serial code configuration file comprises the following steps of S032:
step S032, after the first test bit successfully writes the latest serial code into the memory chip, the latest index value is transmitted to the central server, and the central server writes the latest index value into the serial code configuration file.
Specifically, the sequence code configuration file has two functions, one of which is used for recording a sequence code index range, including an index start value, an index end value and an index mark; the index start value and the index end value determine the boundary which can be set by the sequence code, the minimum is 1, and the maximum is 0xFFFFFFFF (16-system); the index mark is used for automatically setting the format of the sequence code and distinguishing products of different batches with different production dates, for example, the index mark is marked by using system time, a network port IP and serial port numbers so as to distinguish samples of different machines in different time volume production. The other function of the sequence code configuration file is used for synchronizing the current latest index value, and after the test bit successfully writes the latest sequence code into the memory chip, the current latest index value is transmitted to the central server and written into the sequence code configuration file, so that the latest index value is increased backwards according to the latest index value when the next sequence code is obtained; it is understood that in other embodiments of the present invention, two sequence code profiles may be further configured to implement the above two functions respectively.
Example four
In an embodiment of the invention, referring to fig. 1, after the step of returning the latest serial code to the test bit corresponding to the first serial code acquiring signal in the stack area, the method further includes step S04:
step S04, deleting the current first sequence code acquisition signal in the stack area to obtain a new first sequence code acquisition signal. In order to ensure that a test bit corresponding to the first sequence code acquisition signal does not repeatedly acquire the sequence code, the current first sequence code acquisition signal in the stack area may be deleted to acquire a new first sequence code acquisition signal, for example, if the current first sequence code acquisition signal in the stack area is a and the second sequence code acquisition signal is B, after the central server returns the latest sequence code to the test bit corresponding to the first sequence code acquisition signal in the stack area, the signal a in the stack area is deleted, and at this time, the signal B automatically becomes the new first sequence code acquisition signal.
