Silicon Motion 6nm UFS 4.0 Controller for AI Smartphones, Edge Computing and Automotive Applications

Silicon Motion Technology Corporation introduced its UFS (Universal Flash Storage) 4.0 controller, the SM2756, as an industry’s broadest merchant portfolio of UFS controller solutions for the growing requirements of AI-powered smartphones as well as other high-performance applications including automotive and edge computing.

The company also added a new 2nd-gen SM2753 UFS3.1 controller to broaden its portfolio of controllers now supporting UFS4.0 to UFS2.2 standards. The firm’s UFS portfolio delivers high-performance and low power embedded storage for to mainstream and value mobile and computing devices, supporting a broad range of NAND flash, including next-gen fast 3D TLC and QLC NAND.

The SM2756 UFS 4.0 controller solution is an advanced controller, built on 6nm EUV technology and using MIPI M-PHY low-power architecture, providing the right balance of high performance and power efficiency to enable the all day computing needs of today’s premium and AI mobile devices. The SM2756 achieves sequential read performance exceeding 4,300MB/s and sequential write speeds of over 4,000MB/s and supports a broad range of 3D TLC and QLC NAND flash with densities of up to 2TB.

The 2nd-gen SM2753 UFS 3.1 controller solution boasts a fast serial-link-based MIPI M-PHY HS-Gear4 x 2-lane, and SCSI architecture model (SAM) enabling performance. Following the company’s SM2754 UFS3 controller, the SM2753 features single channel design offering a sequential read performance of 2,150MB/s and sequential write performance of 1,900MB/s using next-gen 3D TLC and QLC NAND to address the increasing UFS3 market for mainstream and value mobile phones, IoT and automotive applications.

The company’s latest UFS controller solutions are equipped with LDPC ECC technology and SRAM data error detection and correction. These features enhance data reliability, improve performance, and reduce power consumption. The latest UFS controller solutions support a wide range of NAND, including the latest 3D TLC and QLC NAND flash from all flash makers.

“Our 6nm EUV SM2756 addresses the needs of the latest premium smartphones requiring high performance, high capacity, and low power NAND storage to meet the needs of next gen AI functionality and applications,” said Nelson Duann, SVP, client and automotive storage business. “Our new single channel SM2753 enables us to extend our leadership in the large and growing UFS3 market with a more cost effective, high performance and low power controller.”
