Abstract: A SRAM system which provides for reduced power consumption. The SRAM system utilizes an array of bit cells. Columns of bit cells in the array are partitioned into sections. Each section of bit cells shares a local bit line. A sector select circuit provides for precharging the local bit lines. The sector select circuit also includes a mux for connecting a local bit line to a global bit line. The sector select circuit includes a device for detecting when a sector select signal and a column select signal are present. When both of these signals are present the sector select circuit couples the local bit line with the global bit line, and disengages the precharging of the local bit line.
