Title: In-Nan Wu: Innovator in Memory Systems and Output Buffer Circuits

Introduction

In-Nan Wu is a notable inventor based in Sunnyvale, CA, who has made significant contributions to the field of memory systems and output buffer circuits. With a total of 3 patents to his name, Wu's innovations have advanced technology in various applications.

Latest Patents

One of Wu's latest patents is the "Expanded Cache Memory System." This invention provides an extended memory capability without necessitating a much faster cache memory. It achieves this by incorporating address latches on the same chip as the cache memory, allowing the most significant address bit from the address latches to be combined with the output of appropriate interface logic. The result is an address control signal that can be sent to the memory without requiring as long an access time as the rest of the addresses.

Another significant patent is the "Pulsed Bootstrapping Output Buffer and Associated Method." This output buffer circuit is designed for use with a first external voltage that provides voltage at a first level. The circuit includes an output terminal, a second voltage supply for providing voltage at a second level less than the first level, and various transistors that work together to manage the output voltage effectively. The design includes a bootstrapping turn-on circuit that raises the gate of the n-channel pull-up transistor to a voltage level above the first voltage level, ensuring efficient operation.
