PURPOSE: A nonvolatile memory device is provided to reduce an area of a memory by arranging a row data buffer array near a DQ pad. CONSTITUTION: A nonvolatile memory device includes a bank and a data input/output unit(700). The bank outputs sensed data with a plurality of unit cells into a global input/output line(GIO). The same data as the data stored in the unit call of the bank is stored in a register. A data input/output unit stores data applied from the outside in the register in a write operation and outputs the data stored in the register to the outside in a read operation. The register includes a row data buffer.
