Latest Patents

One of his latest patents is titled "Bitline Precharge Matching." This invention involves a memory device that includes a sense circuit comprising a sense amplifier, a reference sense circuit, and a comparator. The sense amplifier detects a signal on a bit line associated with a column of memory cells in a memory array. The reference sense circuit detects a signal on a reference bit line associated with a column of reference cells in the memory array. The comparator compares the outputs of the sense amplifier and the reference sense circuit, providing a signal indicative of the contents of the read memory cell. In response to a transition of an address, the bit line and the reference bit line are precharged prior to reading the memory cell. The reference sense circuit includes a selectable load that is disabled during the initial time after the address transition, allowing the bit line and the reference bit line to rise substantially identically before enabling it to allow the reference bit line to settle to a steady state.

Another significant patent is for a "Circuit for Transferring High Voltage Video Signal Without Signal Loss." This circuit enables the transfer of high voltage analog video signals while using conventional low voltage logic levels. It includes a first transistor powered by a high voltage power source to bias a pass transistor at a high voltage level. The pass transistor receives a high voltage video signal and, due to the high voltage bias, is able to pass the video signal without attenuation from feedthrough effects, thus preserving the fidelity of the video signal. A second transistor provides a ground potential to turn OFF the pass transistor, disabling the transfer of the video signal. A third transistor operatively coupled to the first transistor turns OFF the first transistor when the second transistor is in operation.
