Abstract:
In one embodiment, a static random access memory (SRAM) device is provided. The SRAM device comprises a plurality of memory cells, a bit line coupled to a first set of the plurality of memory cells at data nodes, and a first voltage supply line coupled to a second set of the plurality of memory cells. The SRAM device further comprises a first switch for selectively coupling the first voltage supply line to a first voltage source to charge the first voltage supply line to a first voltage level and a second switch for selectively coupling the first voltage supply line to the bit line for pre-charging the bit line to a bit line voltage level that is less than the first voltage level.
