Title: **Paul M Goodwin: A Pioneer in Memory System Innovations**

Introduction

Paul M Goodwin, located in Littleton, MA, is a prominent inventor known for his significant contributions to computer memory systems. With a remarkable portfolio that includes 21 patents, Goodwin has dedicated himself to enhancing the efficiency and performance of computing technologies.

Latest Patents

Among his most recent innovations are two notable patents that tackle challenges in memory organization and data latency. The first, titled "Cache Memory Exchange Optimized Memory Organization for a Computer System," addresses data coherency in multiprocessor systems. This innovative design minimizes data latency by utilizing fill requests from any multiprocessor CPU. This method ensures that the information is acquired through the crossbar switch from the same memory module to which the victim data in the CPU's cache must be rewritten. By optimizing this arrangement, Goodwin effectively reduces rewrite latency periods within the crossbar switch, successfully avoiding the 'ships crossing in the night' problem.

The second patent, "Memory Refresh Control System," outlines an advanced memory system featuring a plurality of interleaved memory ranks using SDRAMs that require periodic refresh. This system includes an arbiter that controls access to these memory ranks, effectively managing access during memory refresh periods. The arbiter broadcasts both refresh signals and addresses across a transaction bus, allowing for the sequential refreshing of memory ranks without ongoing control, thereby improving the overall efficiency of the memory module.

Career Highlights

Goodwin's illustrious career includes significant roles at well-respected companies, such as Digital Equipment Corporation and Compaq Computer Corporation. His expertise in memory systems has not only shaped his professional journey but has also influenced the evolution of computer technology.
