Enhanced NVMe SSD Controllers

Capable of PCIe 3.0 X 4 end points providing a 4GB/s interface to host

High performance PCIe SSD Controllers

The 88SS1092 and 88SS1093 are Marvell NVM Express (NVMe) SSD controllers capable of PCIe 3.0 X 4 end points providing a 4GB/s interface to host. These controllers advance a solid-state storage system to a fully Flash-optimized architecture and unleash performance without limits. Both also have 3rd-genaration Marvell LDPC technology for reliability enhancement, endurance boost and TLC NAND device support on top of MLC NAND.

The NVMe (non-volatile memory) design of these controllers has passed through in-house validation and 3rd-party OS/platform compatibility testing to boost next-generation PC and Storage systems.
