Latest Patents
One of his notable inventions is the "Precharged Adiabatic Pipelined Logic." This invention relates to an implementation of adiabatic circuitry using a pipeline structure that allows for simultaneous evaluation of cascaded functions. It does not require each logic function to be implemented in dual complimentary circuitry, reversible logic functions, or the use of diodes to ensure adiabatic current flow. A significant feature of this invention is the use of a six-phase clock cycle associated with six phases of circuit operation, including a precharge phase, a precharge disable phase, an evaluate phase, a hold phase, a precharge enable phase, and a guard phase. Another significant feature is the simultaneous evaluation of cascaded logic functions during a single phase of operation.
Another important patent is the "Verifiable Security Circuitry for Preventing Unauthorized Access." This security system is designed for programmable read-only memory locations within a very large scale integrated (VLSI) circuit. It includes a selection logic that is electrically coupled to multiple security bit memory locations, allowing for the generation of a security access signal. The access logic prevents any device outside the VLSI circuit from gaining direct access to the programmable read-only memory locations based on the security access signal.
