SM2322 USB 3.2 Gen2 x2 可攜式 SSD 控制晶片
The SM2322 is Silicon Motion's new-generation single-chip portable SSD controller, which interfaces directly
with the host, eliminating the need for an external bridge chip. This simplification not only reduces design
complexity and the Bill of Materials (BOM) cost for manufacturers of external SSDs but also accelerates
development timelines and lowers system-level costs, offering significant advantages to customers. The SM2322 is the industry's fastest single-chip high-performance, low-power, and cost-effective solution,
supporting up to 8TB of storage and achieving unparalleled data transfer rates of 20Gbps for storing and accessing large amounts of content seamlessly from AI smartphones, high-performance multimedia devices,
and game consoles.
With the increase of AI-capable devices, high-density and high-performance storage solutions are becoming more critical to consumers. The SM2322 is equipped with a USB 3.2 Gen2x 2 interface with 20Gb/s bandwidth and a fully integrated hardware and software solution that provides four NAND channels capable of faster data rates of up to 1,200 MT/s per channel, delivering peak sequential read and write transfer speeds of 2,100MB/s and 2,000MB/s, respectively. With this, it supports the latest TLC/QLC NAND and is ready to adapt to future NAND I/O speed advancements, offering blazing-fast data transfer with up to 8TB high capacity in a compact form factor. It effectively meets the customer’s need for faster data access and larger capacity.
Leveraging Silicon Motion’s proprietary NANDXtend® 4KB LDPC error-correction technologies, the SM2322
enhances the endurance and data retention of 3D TLC/QLC NAND. It provides comprehensive assurance of
data integrity through SRAM ECC and end-to-end data path protection.
In addition, the SM2322 delivers the highest level of data security by providing AES 256-bit encryption,
fingerprint security, and full compliance with the Trusted Computing Group (TCG) Opal specification to meet
the AI data storage required high-security standards.
