With the continuous increase of the requirements of data storage capacity and storage speed, the traditional server load capacity reaches the limit. Especially, the memory capacity of the server cannot be greatly improved due to load limitation, and the power consumption of the traditional server memory is huge because the traditional server memory needs to be continuously self-refreshed due to the working principle of the traditional server memory, and meanwhile, more powerful heat treatment equipment is needed for heat dissipation of all devices of the server, otherwise, the server is unstable.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: a low-load 64GB capacity new server memory bank is shown in figure 1,
Fig. 2 shows that the electronic device comprises an electronic circuit board 1, wherein the electronic circuit board 1 is provided with a memory chip module 2, a read-write error correction module 3, a mode register module 4 and a golden finger 5 through circuit connection, and a part of the golden finger 5 corresponds to the typically connected read-write error correction module 3 and the mode register module 4.
Preferably, two read-write error correction modules 3 are arranged and respectively arranged on the front side and the back side of the electronic circuit board 1.
Preferably, the mode register module 4 is disposed on the front surface of the electronic circuit board 1.
Preferably, the distribution of the memory chip modules 2 on the electronic circuit board 1 adopts a staggered arrangement mode.
As shown in fig. 1, the memory chip modules 2 are distributed in a staggered arrangement manner, so that for a 64GB memory with a relatively large capacity, a circuit board per unit area can accommodate more memory particles, and it is possible to realize a large capacity of 64 GB.
The DDR4 DRAM dynamic random access memory particle based on the 2Z nanometer manufacturing technology has the single particle capacity reaching 16Gb, the working voltage stabilizing at 1.20V, and is one of the leading DRAM particles.
Compared with the parity check technology which can only check errors, the server memory adopts a mode register control chip and an ECC error check and correction technology. The method adds an error correction function, so that data can be corrected by itself under the condition of read-write errors, and the normal operation of the server is ensured.
In addition, compared with a common memory 8 physical Rank, the newly developed server memory adopts 2-4 physical ranks, so that the working controllability of the server memory is stronger, and the server memory can communicate with external equipment more quickly.
Compared with a normal Unbuffered DIMM, the Registered DIMM used by the server improves the memory support capacity by buffering signals on a memory strip and redriving memory granules, and the LRDIMM memory reduces the load of a memory bus by changing a Register chip on the current RDIMM memory into an IMB memory isolation buffer chip and correspondingly further improves the memory support capacity. Compared with the common RDIMM, the power consumption of the memory of the 2Rank LRDIMM is only 50% of that of the memory, and the power consumption of the memory of the 4Rank LRDIMM can be as low as 75% of that of the memory of the 4Rank LRDIMM.
the product adopts a novel architecture form, and the architecture form has a new breakthrough. The original common processor can support 3 memory channels, each memory channel can support at most 3 RDIMMs, and after the LRDIMM memory adopting the new architecture is adopted, the same system can support 9 DIMMs per channel, and the memory capacity is improved to three times.
