Marvell Announces NVMe Controller for DRAM-Less PCIe 3.0 x2 SSDs
 

Marvell has announced its new controller for affordable and miniature SSDs, the 88NV1160. The chip can be used to build small form-factor SSDs in M.2 as well as BGA packages. The 88NV1160 supports all modern and upcoming types of NAND flash, LDPC error correction, NVMe protocol and other advantages of modern SSD controllers, but it does not require external DRAM buffers so to reduce BOM costs of upcoming SSDs.
