Abstract
A novel and useful mechanism for reducing current leakage in a static random access memory array which significantly reduces the power requirements of the memory array. The method enables the steady state of all local and global bit lines in an SRAM array to be discharged during both active and inactive modes. The memory array includes memory cells having an N channel field effect transistor read stack. A mechanism is provided to evaluate data from memory cells where the steady state of local and global read bit lines is discharged.
