Abstract
Systems and method for reducing leakage currents and power consumption in a memory array comprising memory cells, such as 8T SRAM cells. The memory array includes logic for dynamically placing a group of memory cells in the memory array in a reduced power state during sleep mode or inactive states of the group of memory cells, such that leakage parts are effectively eliminated. The memory array further includes logic for dynamically enabling a selected group of the memory cells during read or write access operations on the selected memory cells, wherein corresponding read or write bitlines are precharged before and after the respective rear or write operations.
