ABSTRACT:
Disclosed herein is an integrated circuit memory device which includes a memory cell arranged at an intersection of a word line and a bit line and a bit line precharge circuit for providing the bit line with a predetermined current during respective bit line precharge and sensing periods of time of a data reading operation in response to a bit line precharge signal. The integrated circuit memory device further includes a bit line pass transistor which has a gate and connected between the bit line precharge circuit and the bit line and which transfers the current from the bit line precharge circuit onto the bit line. Furthermore, the device includes a bias voltage supplying circuit which supplies the gate of the bit line pass transistor with a bias voltage during the data reading operation. In this embodiment, the bias voltage supplying circuit makes a voltage on the gate of the bit line pass transistor become discharged under the bias voltage during a bit line discharge period of time of the data reading operation.
