Abstract
A static random access memory (SRAM) is laid out to be balanced so that, when power is applied to the SRAM, the cells of the SRAM have no preferred logic state, In addition, the SRAM is fabricated in a process the emphasizes mismatches so that each individual cell assumes a non-random logic state when power is applied.
