Title: Write driver controll circuit for sram
Inventor: SON JONG HO
IPC: G11C11/413
Filed: 2001-10-23
Abstract: PURPOSE: A write driver control circuit of an SRAM is provided to perform a stable write operation under low voltage by preventing a write operation of error data on a cell due to the internal timing. CONSTITUTION: A write timing signal generation portion(400) generates a write timing control signal for controlling the write timing. The first inverter(42) is used for inputting an address transition detection signal. An error data prevention portion(410) receives an output signal of the first inverter(42) and an error data prevention signal and generates a low signal during a predetermined time regardless of the address transition detection when the error data prevention signal is generated. A selection portion(420) outputs selectively one of an output signal of the first inverter(42) and an output signal of the error data prevention portion(410). An output portion(430) generates a write driver control signal of the second voltage level when the write timing control signal and the output signal of the selection portion(420) have the first voltage level.
