A nonvolatile memory device is provided relating to a test operation for a Low Power Double-Data-Rate (LPDDR) nonvolatile memory device. The nonvolatile memory device comprises a command decoder configured to decode a test mode signal in a test mode to output program and erasure signals into a memory, an address decoder configured to decode a command address inputted through an address pin in the test mode to output a cell array address into the memory, and an overlay window configured to store a data inputted through a data pin in the test mode.
