DRAM-less SSD Controllers
Optimized for a new generation of slim computing devices
The 88NV1120 and 88NV1160 comprise the first Marvell family of NVM Express DRAM-less SSD controllers supporting 6Gb/s SATA, PCIe Gen3x1 and PCIe Gen3x2 interface respectively for small-form-factor and value line SSD markets.
In addition to value-line SSD enabling, the 88NV11xx family design is also optimized for small form factor applications. By using 28nm CMOS process node technology, the controller is perfect for multiple-chip-package (MCP) integration running on embedded SRAM without external memory. It’s perfect for low-z-height or compact mobile devices looking for SSD performance, like premium tablet or 2-in-1 notebook. The standalone packed version also help enable modules as small as M.2 2230 (3cm in length). And an integrated solution with NAND (so-called BGA SSD), 11.5x13mm and 16x20mm form factors are supported.
The 88NV1160 supports the NVM Express standard or legacy AHCI through PCIe interface and the Host Memory Buffer feature can boost Random Read/Write performance. The 88NV1120 supports popular SATA interface in a client PC system. The controllers are all equipped with Marvell NANDEdge™ LDPC error correction technology for reliability enhancement, endurance boost and supports 15nm 2D TLC and 3D TLC/QLC.
