Title: David W Williams: Innovator in Memory Transistor Technology

Introduction

David W Williams is a notable inventor based in Baltimore, MD (US), recognized for his contributions to memory transistor technology. With a total of 5 patents to his name, Williams has made significant advancements in the field of electronics, particularly in the development of methods for improving memory transistors.

Latest Patents

One of his latest patents is titled "Method of making self-aligned memory MNOS-transistor." This innovative method describes a technique for positioning the variable threshold region of a memory transistor at a predetermined distance from the drain and source regions. The process involves creating openings in the dielectric material over the substrate simultaneously for both the variable threshold region and the drain and source regions. A mask is then positioned over the variable threshold region opening while the drain and source regions are formed. The variable threshold region is subsequently created by growing thin oxide and a layer of nitride over it. This invention addresses the challenge of providing additional space for alignment tolerances between the variable threshold region and the drain and source regions.

Another significant patent by Williams is the "Automatic data restore apparatus for MNOS temporary store memory." This apparatus utilizes a pair of memory transistors along with a dual node detection circuit that drives two cross-coupled NOR gates, effectively providing a temporary store memory unit.
