Abstract
An SRAM, which includes a plurality of bit line pairs, a memory cell connected between each pair of the bit lines, and an address transition detection circuit for detecting transition of the externally applied address signal to generate a detection pulse signal, is provided with an improved bit line precharge circuit requiring only two transistors per bit line pair. The new precharge circuit is controlled by a bit line precharge control signal generator for generating a control signal determined by a ratio of impedances connected between a source voltage and ground voltage.
