Title: Walter Lee McNall: Innovator in Semiconductor Technology
Introduction
Walter Lee McNall is a notable inventor based in Meridian, ID (US), recognized for his contributions to semiconductor technology. He holds a total of 5 patents, showcasing his innovative approach to system-on-chip design and die authentication.
Latest Patents
Among his latest patents is a method and apparatus for validating a system-on-chip based on a silicon fingerprint and a unique response code. This invention includes a system-on-chip that comprises circuit instances, a selector module, a circuit instance module, and a comparing module. The circuit instances are designed to provide nominally the same value at each of their nodes. The selector module generates a selection signal, while the circuit instance module monitors the states of the nodes and selects parameter values based on the selection signal. The comparing module then compares these states or parameter values and outputs either a silicon fingerprint or a unique response code of the system-on-chip.
Another significant patent by McNall is a method and apparatus for authenticating a semiconductor die. This invention describes techniques for device-based die authentication, where the intensity of a particle beam is varied during semiconductor processing. This results in semiconductor dies with devices that vary in value, enabling subsequent authentication based on the generated values associated with each die.
