The Silicon Motion SM2268XT is the company’s latest PCIe Gen4 SSD controller solution designed for higher-speed NAND transfer rates. The new controller is optimized for current and future TLC and QLC 3D NAND flash and enables high-value SSDs for a broader range of laptop PCs, including performance, mainstream, and value-based solutions.
The SM2268XT features a dual-core ARM R8 CPU with four lanes of 16Gb/s PCIe data flow and supports four NAND channels with up to 3,200 MT/s per channel. Its multi-core design automatically balances the compute load to deliver quoted sequential read and write speeds up to 7,400MB/s and 6,500MB/s, respectively, with random performance expected to hit up to 1,200K IOPS.
Silicon Motion indicates that this performance and robust reliability will allow designers to accelerate developing next-generation SSDs using current and future TLC and QLC 3D NAND flash without compromising throughput and latency.
Its DRAM-less architecture also means the SM2268XT uses Host Memory Buffer (HMB) and Silicon Motion’s 8th generation NANDXtend to provide burst performance and error correction without the use of a DRAM cache. NANDXtend ECC is Silicon Motion’s advanced error correction technology that uses a performance-optimized 4KB LDPC engine and RAID to maximize data integrity and correction in NAND flash memory.
All of this tech allows companies to offer more cost-effective and power-efficient solutions for high-speed storage in laptops.
