Abstract
An operating method of a data storage device including a plurality of nonvolatile memory devices includes the steps of: mapping physical addresses of the nonvolatile memory devices into logical addresses; reflecting environmental factors to remap a physical address into a logical address requested to be accessed; and performing an interleaving operation for the nonvolatile memory devices using the remapped physical address.
Claims20
An operating method of a data storage device including a plurality of nonvolatile memory devices, comprising the steps of:
- mapping physical addresses of the nonvolatile memory devices into logical addresses;
- reflecting environmental factors to remap a physical address into a logical address that is requested to be accessed;
- and
- performing an interleaving operation for the nonvolatile memory devices using the remapped physical address.
1 more element
A data storage device comprising:
- a plurality of nonvolatile memory devices;
- and
- a controller configured to control operations of the nonvolatile is memory devices,
- wherein the controller maps physical addresses of the nonvolatile memory devices into logical address provided from a host device, remaps a physical address into a logical address requested to be accessed from the host device by reflecting environmental factors of the host device and the nonvolatile memory devices, and performs an interleaving operation for the nonvolatile memory devices using a remapped physical address.
