With the popularity of AMD and Intel support platforms, PCIe 4.0 SSDs have blossomed everywhere, and the master control scheme is constantly iterative. Huirong technology has launched the second generation PCIe 4.0 SSD master chip " sm2269xt ", which is based on the advanced 12NM process , integrates two arm R8 CPU cores, four 16gbps PCIe data flow channels and four NAND flash memory channels. The maximum rate of each channel is 1600mt / s, and supports automatic adjustment of multi-core load.
The master adopts drma less cache free architecture , supports HMB (host memory cache) technology, borrows a small amount of memory, and the sequential read-write performance can reach 5.1gb/s and 4.7gb/s , and the size is smaller.
Huirong also provides a complete commercial ASIC / firmware solution for sm2269xt, supports the latest 3D TLC and QLC flash memory, and supports unique nandxtend ECC error correction technology, 4KB LDPC engine, programmable raid, SRAM ECC, end-to-end data path protection and other technologies.
*Under PS3 light sleep power supply, the power consumption of sm2269xt is only 15MW. Under PS4 deep sleep, it is lower than 1.6MW *, which is far lower than other 28nm master control schemes.
LexA has launched the product " nm760 " using sm2269xt master chip, which supports nvme 1.4 protocol, with a maximum capacity of 2TB, and a new generation of composite heat sink.
