Silicon Motion’s SM2320 native USB 3.2 Gen 2×2 controller for USB flash drives and moveable SSDs has loved nice market success with a lot of design wins over the previous few years. Silicon Motion proudly displayed a collection of merchandise based mostly on the SM2320 on the present flooring at FMS 2024.
The SM2320 went into mass manufacturing in Q3 2021. Since then, the NAND flash market has seen appreciable change. QLC is turning into an increasing number of dependable and customary, resulting in the launch of high-capacity cost-effective four TB and eight TB SSDs. Newer NAND generations with flash working at larger speeds have additionally made an look.
The SM2320, fabricated in TSMC’s 28nm node, supported 4 channels of NAND flash operating at as much as 800 MT/s. The new SM2322 makes use of the identical course of node and retains help for a similar variety of flash channels and chip permits (eight CEs per channel). However, the NAND can now function at as much as 1200 MT/s.
The SM2322 additionally improves the QLC help, due to the implementation of a greater ECC scheme. While the SM2320 opted for a 2KB LDPC implementation, the SM2322 goes in for a 4KB LDPC resolution. The use of a bigger area permits extension of the NAND’s helpful life.
The SM2322 and SM2320 packages are comparable in dimension, and Silicon Motion expects PSSD designs utilizing the SM2320 to undertake the SM2322 with totally different NAND (larger capability / speeds) utilizing the identical enclosure. Products based mostly on the SM2322 are anticipated to look out there earlier than the top of the 12 months.
