High performance address decode technique for arrays

摘要

An address decoder having pre-decode logic circuitry positioned in between ends of final decode logic circuitry is provided. Such an address decoder yields less wire load, less gate load, less power consumption, and increased speed due to the pre-decode logic circuitry having to be capable of only driving a signal over half the length of a final decoder. Further, a method to select memory elements from a memory array using centrally positioned pre-decode logic circuitry is provided.
