Abstract
An extended segmented precharge architecture for static random access memories includes a logic circuitry on an SRAM chip to keep track as to whether a given bit line has been read out. As long as a given bit line has not been read out, precharge of the equalization lines is eliminated thereby increasing access cycle time and reducing power dissipation. The architecture can be applied to any size SRAM of any organization.
