NONVOLATILE MEMORY DEVICE

摘要

PURPOSE: A nonvolatile memory device is provided to reduce a memory operation time by controlling a preparation sequence and a stress sequence of an operating sequence in parallel. CONSTITUTION: A command generator(30) generates commands for executing a memory operation. A command buffer(20) stores the generated commands temporally. A preparation state unit executes a preparation sequence. The stress state unit executes the stress sequence. A logic unit controls an inner operation sequence. The internal operation controller(10) controls the sequence of the internal operation to execute the commands which are stored in the command buffer.
