  • Patent number: 10095626
    Abstract: A solid state drive (SSD) with pseudo-single-level cell (pSLC) caching and a method of caching data in an SSD is disclosed. In one embodiment, the SSD includes a plurality of multibit NAND media devices arranged in one or more channels communicatively coupled to a memory controller. A first portion of the plurality of multibit NAND media devices is configured to operate as a pSLC cache and a second portion of the plurality of multibit NAND media devices is configured to operate as a multibit NAND media storage area. In one embodiment, the pSLC cache comprises a first area for a pSLC write cache and a second area for a pSLC read cache.
