Title: Tricia A Gruwell: Innovator in ECC Logic and Data Bus Steering

Introduction

Tricia A Gruwell is a notable inventor based in Austin, TX, who has made significant contributions to the field of computer memory systems. With a total of 2 patents, her work focuses on enhancing error correction and data routing in computing environments.

Latest Patents

One of her latest patents is a method for testing ECC (Error-Correcting Code) logic. This innovative system checks the test logic within a computer memory system during the Power-On Self-Test (POST). By inducing single and double bit errors, the ECC logic can identify and correct these errors before processing operations begin. The CPU compares the data written to memory with the data read back, ensuring that the ECC correction logic functions correctly. A multiplexer in the data write path substitutes a constant set of identical bits for the actual data generated by the CPU, allowing for effective error identification and correction.

Another significant patent involves steering logic that routes data between various byte lanes of the system bus. This control mechanism enables communication between connected devices and the steering logic, facilitating data transfer during load and store operations. The steering logic includes components such as multiplexers, latches, buffers, and drivers, which work together to ensure efficient data routing, especially when devices of varying data widths are connected to the system bus.
