Abstract
Disclosed is a semiconductor memory device with a reduced write recovery time and an increased refresh period. The semiconductor memory device incorporating a plurality of memory cells therein, including: a bit line sense amplifier (BLSA) array provided with a plurality of bit line sense amplifiers for sensing and amplifying data of the memory cells applied to bit lines; and a BLSA driving control means for overdriving a bit line connected to the bit line sense amplifier in response to an active command, and for overdriving the bit line in response to a precharge command.
