ABSTRACT:
A write driver circuit of a semiconductor memory device having a read/write memory cell array including a plurality of read/write cell blocks each having an input terminal, comprising driver input terminals including a first driver input terminal at which a first driver input signal is to appear and a second driver input terminal at which a second driver input signal is to appear, each of the first and second driver input signals being shiftable between discrete first and second voltage levels, and a plurality of driver circuit sections each having input terminals at the first and second drive input terminals, respectively, and an output terminal connected to the input terminal of each of the read/write cell blocks, respectively. Each of the driver circuit sections is operative to activate the associated one of the read/write cell blocks in the copresence of the first and second driver input signals of the first voltage levels at the first and second driver input terminals, respectively.
