Nonvolatile memory device and related data management method

摘要

A method of operating a nonvolatile memory device comprising a plurality of memory blocks comprises storing first data and second data to be stored in a hot memory block of the memory blocks in a first buffer, transferring the first data stored in the first buffer to a second buffer to program the first data in the hot memory block, and generating RAID parity data based on the first and second data, wherein the RAID parity data and the first data form part of the same write stripe.

1. A memory system, comprising:
a nonvolatile memory comprising a plurality of memory blocks; and a controller configured to control the nonvolatile memory; wherein the controller identifies at least one of the memory blocks as a hot memory block and generates at least first and second RAID parity data based on first data corresponding to a first hot page of the hot memory block, wherein the first data and the first RAID parity data form part of a first write stripe, and the second RAID parity data forms part of a second write stripe different from the first write stripe.
