  • Self-timed address decoder for register file and compare circuit of multi-port cam
    Patent number: 6269045
    Abstract: A circuit evaluates a plurality of data inputs, provides for stabilization of the evaluation, and then drives the evaluation from the circuit. The providing of the stabilization is performed by delaying an activation signal, which controls the evaluation circuitry. The activation signal may be either a clock signal or a reset signal. This circuit may be an address decoder that decodes certain ones of the address signals during the evaluation phase, and then drives the evaluation during the second phase.
    Type: Grant
    Filed: February 8, 2000
    Date of Patent: July 31, 2001
    Assignee: International Business Machines Corporation
    Inventors: Christopher McCall Durham, Peter Juergen Klim, Roy Keith Waite
