ABSTRACT:
A pseudo-static ROM circuit which uses cross-coupled sense amplifiers to provide rapid accesses to ROM stored data, yet because of a special bit line precharger and dummy load arrangement dissipates very little static power. After a stable logic static is attained by the sense amplifier during a READ, the sense amplifier and the precharger-dummy load circuits do not draw any appreciable current or power until the next precharge-and-READ operation is initiated. Therefore, almost all of the power dissipated by the pseudo-static ROM occurs during the dynamic operations of precharging and READing the bit lines.
