Abstract
A host device connected to memory devices, with each memory device having NAND memory chips and an associated controller. Each NAND memory chip can store a page of data in a single write operation, and can read a page of data from NAND memory in a single read operation, with the page being the smallest unit of storage and having a plurality of bits. The controller of each memory chip partitions each page of the associated NAND memory chip into first, second and third locations. The first location is for storage of host data. The second location is for storage of controller meta data. The third location is for storage of meta data of the host device associated with the host data. The host data, meta data of the controller, and meta data of the host device are written into or read from a page in a single operation.
