Silicon Motion sampling new NAND controller

Update: February 21, 2023

The SM2268XT’s allows customers to accelerate development of next-generation SSDs using current and future TLC and QLC 3D NAND flash with comprehensive data integrity and correction without compromising throughput and latency.

The device has  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, enabling designers to take advantage of higher throughput next-generation high-speed TLC and QLC 3D NAND flash. Its multi-core design automatically balances the compute load to deliver industry-leading sequential read and write speeds of 7,400 MB/s & 6,500 MB/s, and random read & write speed of 1,200K IOPS. In addition, its architecture enables lower power consumption and rigorous data protection, providing high performance and reliability in a cost-effective DRAM-less PCIe Gen4 NVMe SSD solution. The SM2268XT offers a new system bus architecture, Host Memory Buffer (HMB) function and Silicon Motion’s 8th generation NANDXtend ECC technology with a performance-optimised 4KB LDPC engine and RAID to maximise error correction capability. The SM2268XT is designed for cost effective TLC and QLC 3D NAND flash to enable high-value SSDs for a broader range of laptop PCs from performance to mainstream to value. Silicon Motion is currently sampling SM2268XT to key customers.  More information about this and the company’s other PCIe Gen4 SSD controllers can be found at www.siliconmotion.com
