Marvell today announced the world’s first DRAM-less NVMe (Non-Volatile Memory Express) solid state drive (SSD) controller for mass market mobile computing solutions with NANDEdge low-density parity check (LDPC) technology supporting triple-level cell (TLC) and 3D NAND.
Marvell’s 88NV1140 and 88NV1120 enable small form factor SSD solutions with unparalleled performance for integration into low-z-height tablets, Chrome devices and the upcoming wave of new 2-in-1 hybrid/detachable mobile PC platforms.
The small form factor of Marvell’s 88NV1140 and 88NV1120 at 8x8mm per package allows SSD drives as small as M.2 2230 (30 mm in length). In addition, the new controllers can enable the development of an NVMe BGA or SATA BGA SSD running on embedded SRAM through multiple-chip-package (MCP) integration with NAND.
Utilizing 28 nm low-power CMOS process node technology, the 88NV1140 and 88NV1120 controllers are best-in-class in active power while supporting all low power modes (L1.2 for PCIe and DevSlp for SATA devices). Both new solutions share Marvell’s third-generation NANDEdge error-correction technology, as with the previously announced 88SS1093 PCIe Gen3x4 NVMe and 88SS1074 SATA SSD controllers.
By developing single code for NANDEdge, SSD firmware developers are able to rapidly leverage one code to the other for advanced error-correcting technology for data integrity, endurance and reliability. In addition, Marvell’s NANDEdge LDPC technology can support 15/16nm TLC and 3D NAND.
