The first is the SM2504XT, an ultra-low power PCIe Gen5 DRAM-less controller offering industry-leading performance per watt, while the second is the SM2324, said to be the world’s first true single-chip portable SSD controller supporting USB4 with built-in Power Delivery.
These new products are intended to provide energy-efficient, high-performance SSD solutions for AI PCs, gaming systems, and portable devices.
Built on TSMC’s 6nm process, the SM2504XT delivers up to 11.5 GB/s sequential read and 11.0 GB/s write speeds, with random IOPS reaching up to 1.7M read and 2.0M write, while consuming under 5W. Compared to the previous generation, it achieves an 11% performance gain per watt and delivers improved levels of power efficiency among PCIe Gen5 client SSD controllers.
Supporting PCIe Gen5 x4 and NVMe 2.0, the controller is intended for DRAM-less SSDs in AI PCs, notebooks, and gaming systems. It incorporates a Separate Command Address (SCA) architecture for reduced latency, and supports the latest 3D TLC and QLC NAND, meeting the growing demand for cost-effective, high-performance, and energy-efficient SSD solutions.
The SM2324 is a single-chip portable SSD controller that combines native USB4 support with a a built-in Power Delivery controller. Delivering sequential read/write speeds of up to 4,000MB/s and optimised for 3D TLC and QLC NAND, the SM2324 supports storage capacities of up to 32 TB.
Its single-chip architecture reduces BOM cost and simplifies design, accelerating time-to-market for OEMs building compact, high-speed portable drives.
