Taipei and Milpitas, California, United States. 16 February 2023 – Silicon Motion technology corporation, a provider in designing and marketing NAND flash controllers for solid state storage devices, has announced the SM2268XT, its high performance PCIe Gen4 SSD controller solution optimised for higher speed NAND transfer rates. The SM2268XT’s performance and robust reliability allows customers to accelerate development of next generation SSDs using current and future TLC and QLC 3D NAND flash with data integrity and correction without compromising throughput and latency.
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, 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 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 accurate 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 next generation, 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.
“We are proud to introduce the SM2268XT for Client SSDs,” says Wallace Kou, president and CEO of Silicon Motion. “We have been scaling our SSD controller design wins with leading PC OEMs, and this latest evolution of our PCIe Gen4 controllers demonstrates our commitment to developing products these customers want and need to support future higher speed NAND.”
“We are excited about this high-performance PCIe Gen4 controller from Silicon Motion,” says Atsushi Inoue, senior director, memory division, KIOXIA Corporation, “We believe that SM2268XT will upgrade the standard of high-performance SSDs to the next level together with our leading BiCS FLASL technology.”
“PCIe Gen4 SSDs are experiencing explosive growth with shipments almost doubling in 2022 and will continue to be the mainstay storage solution in PCs for the next few years,” says Greg Wong, president of Forward Insights. “Silicon Motion’s latest SM2268XT DRAM-less controller enables cost-effective, high-performance storage in PCs supporting the most advanced 3D NAND technologies.”
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 here
