  • Patent number: 11551752
    Abstract: A nonvolatile memory apparatus performs a plurality of read operations by using a plurality of read voltages. A first read operation is performed by applying a first read voltage to a memory cell. A second read operation is selectively performed based on whether a snap-back of the memory cell occurs during the first read operation. The second read operation is performed by applying a second read voltage having a higher voltage level than the first read voltage to the memory cell.
