DRAMless Architecture with Host Memory Buffer (HMB)

Solid State Drive (SSD) without on-board DRAM, also known as DRAMless SSD is widely adopted across personal computer (PC) and embedded markets. As SSDs scale to multi-terabyte capacities, conventional SSD architecture that are dependent upon DRAM present challenges with respect to bill of material (BOM) costs, power consumption, thermals, and the increasing need to provide small form factor SSDs such as M.2 2230 and BGA. TenaFe’s technology breaks through these barriers with its TC2200 DRAMless controller solution by offering impressive performance capabilities of up to 4.8GB/s at less than 4.0W active power with leverage of Host Memory Buffer (HMB) feature. The outstanding performance, combined with best-in-class power and thermal efficiencies, makes it ideal for devices such as ultra-portable laptops, gaming consoles, and edge computing platforms. In addition, TenaFe’s TC2200 controller features FlexLDPC technology, a proprietary LDPC error correction engine which provides for best-in-class latency, quality of service (QoS), and endurance for the latest TLC and QLC NAND Flash technologies.
