PURPOSE: A nonvolatile memory device with a variable operation speed and a complementary signal controlling method therefor are provided to minimize current consumption by controlling a disable timing of the complementary signal in an asynchronous mode operation. CONSTITUTION: A nonvolatile memory device operates at a first operation mode and a second operation mode. A controller(410) enables a complementary signal input and output buffer in response to an entry instruction to the first operation mode. The controller disables the complementary signal input and output buffer in response to a transition instruction to the second operation mode. A nonvolatile memory module(420) is used as a data storage area.
