SEMICONDUCTOR MEMORY DEVICE

摘要

PURPOSE: A semiconductor memory device is provided to decrease a bit line equalizing time by distributing a plurality of pull-up transistors driving a bit line equalizing signal line in a conjunction region. CONSTITUTION: A semiconductor memory device includes a sub word decoder region(120), a bit line equalizing and sensing amplification region(140), and a conjunction region(160). A main word decoder circuit selects a cell array(100). A bit line equalizing signal generation circuit generates a bit line equalizing signal for controlling a transistor for precharge and equalizing offered to the bit line equalizing and sensing amplification region(140). A plurality of pull-up drivers drives a signal line for transporting the bit line equalizing signal with an established voltage.
