Introduction

Zhen Wu Liu is a notable inventor based in Sunnyvale, CA, with a focus on advancements in electronic circuitry. He holds a total of 4 patents, showcasing his contributions to the field of technology and innovation.

Latest Patents

One of Liu's latest patents is titled "Adaptive timing control circuitry to address leakage." This invention presents circuits, methods, and systems designed to manage current leakage in electronic circuits. The circuit includes a keeper circuit and a controller. The keeper circuit supplies current to a leaker circuit that is experiencing current leakage, compensating for the leakage. The controller provides a control signal to the keeper circuit based on the current leakage, with the control signal's cycle matching that of a clock signal. The keeper circuit delivers current to the leaker circuit during a specified period while withholding it during another, with the durations determined by the current leakage.

Another significant patent is the "Method for performing swap operation and apparatus for implementing the same." This invention enables the provision of requested data within two clock cycles when executing a swap operation between an accessible memory cell and a background memory in a computer. In the first clock cycle, the memory addresses for the swap operation are decoded. During the high phase of the second clock cycle, requested data is restored from the background memory to the accessible memory cell, ensuring no data loss due to duplication in a shadow memory cell. The requested data becomes available for reading in the low phase of the second clock cycle.
