Latest Patents

One of his latest patents is a "Word line driver for semiconductor memories." This invention features a hierarchical word line driving structure that utilizes a shared inverter circuit architecture. This design allows for lower power consumption and employs a pulsed control signal to ensure accurate memory retrieval. The structure includes a row decoder, a first sub-word line driver, a second sub-word line driver, and an interconnect line. The first sub-word line driver incorporates an inverting circuit for inverting the signal along the global word line, while the second sub-word line driver does not. The interconnect line facilitates communication of the inverted signal between the two sub-word line drivers. Additionally, a pulsed control signal is supplied to clamping transistors connected to unselected word lines to ensure they remain clamped to ground.

Another significant patent is the "High speed low power amplifier circuit." This amplifier circuit is designed to maintain high speed while reducing power consumption, even when operating at lower voltages. The circuit includes a set-up circuit that performs a level shift on the input signal and applies it to the inputs of a sense amplifier in a cross-coupled manner. The design allows one leg of the precharged sense amplifier output to discharge in response to the input without a counteracting charging action from the other leg, enabling higher speed operation without crowbar current, even with smaller input signals.
