Abstract

An arbitration circuit and method for a multiport high speed memory in a computer microprocessor. A plurality of addresses are provided to a plurality of ports. The addresses are decoded in a plurality of decoders. The decoded output lines are compared in a comparison circuitry to determine if one or more of the ports is requesting access to the same memory line, and a comparison bit indicative of a match is outputted. If asserted, the comparison bit disables a line driver so that only one of the wordlines in a particular memory line is driven at any one time.
