1. A memory system, comprising:

  • nonvolatile memory cells each configured to store more than one bit of data;

    dummy memory cells; and

    a controller configured to control application of voltages to gates of the nonvolatile memory cells and the dummy memory cells, such that during an operation to read data from a group of the nonvolatile memory cells that are adjacent to the dummy memory cells, a read voltage is applied to the gates of the nonvolatile memory cells in the group while a first voltage is applied to gates of the dummy memory cells and a second voltage is applied to the other groups of the nonvolatile memory cells, the first voltage being higher than the second voltage.
