PURPOSE: A semiconductor memory device is provided to reduce the area of a whole bank by including a write driver control circuit. CONSTITUTION: In a semiconductor memory device, a plurality of banks(B0~B3) read/write data in/from a unit cell. Write driver controllers(200,300) outputs a control signal. The control signal controls the write driver. The write driver controllers are shared by a plurality of banks. A command circuit unit(100) outputs a bank select signal and a control signal in the write driver controller. The control signal controls wiring data. |
