Latest Patents

One of his latest patents is the Dual Look Ahead Mask Generator. This innovative device generates a mask that has logical signals of a given level between positions indicated by beginning and ending addresses. The design includes two decoders that select respective binary signal lines indicating the starting and ending positions. The mask generator consists of two mask generators that operate on the higher and lower order binary signal lines, which ripple from the ends of the mask towards the middle. Each of the dual mask generators is equipped with look-ahead carry capability, enhancing its functionality.

Another significant patent is the Laser Cut Storage Cell. This invention utilizes a residual charge bleed-off diode connected to the gate of an FET device in a Read Only Storage (ROS). The ROS is personalized by cutting selected gate leads in an array of FETs using a laser beam. This method addresses the issue of static electric charges on the lead, which become isolated at the gate after cutting, leading to unpredictable conduction states. By incorporating a bleed-off diode, the charges can leak away from the FETs whose gates have been cut, while preventing the voltage of the FET gate from floating. This design minimizes the diode's effect on circuit speed when the gate remains connected to the rest of the read-only storage circuitry.
