Abstract

A mass storage memory device is disclosed. The device includes a nonvolatile memory, a volatile memory configured to store logical to physical (L2P) data associating logical addresses of data stored in the nonvolatile memory with physical locations of the nonvolatile memory at which the data is stored, and a controller. The controller writes L2P data in the nonvolatile memory so the L2P data can be preserved through a power failure. The controller also writes L2P data stored in the nonvolatile memory to the volatile memory to rebuild the L2P table.
