1. A nonvolatile memory system, comprising:

  • a nonvolatile memory device that comprises a nonvolatile memory cell array and a page buffer internally connected to bit lines of the nonvolatile memory cell array, wherein the page buffer is disposed inside the nonvolatile memory device and the page buffer buffers data while the data is programmed into the memory cell array or while the data is read from the memory cell array; and

    a memory controller that transmits a first command to the nonvolatile memory device such that the nonvolatile memory device loads into the page buffer mapping data that is stored in the nonvolatile memory cell array, receives a logical address from outside the memory controller after the mapping data is loaded into the page buffer, and transmits a second command to the nonvolatile memory device if it is determined that the mapping data includes mapping information for the logical address,wherein the page buffer of the nonvolatile memory device transmits the mapping data to the memory controller in response to the second command, and the memory controller translates the logical address into a physical address based on the mapping data that is received from the page buffer.
