Title: Morgan J Dempsey: Innovator in Cache Memory Technology
Introduction
Morgan J Dempsey is a notable inventor based in Phoenix, AZ, with a focus on advancements in cache memory technology. He holds a total of 7 patents that contribute significantly to the field of integrated circuits and memory reliability.
Latest Patents
Among his latest innovations is a patent for "Repair bits for a low voltage cache." This invention describes a method and apparatus for repairing cache memories and arrays. The cache includes multiple lines that are logically viewable in columns. A repair cache is coupled to the cache, featuring a repair bit mapped to each logically viewable column. The repair module identifies a bad bit to be repaired within a column based on various factors, such as the number of errors per line and the failure rate of bits. The bad bit is transparently repaired by the corresponding repair bit upon accessing a cache line that includes the bad bit.
Another significant patent is for a "Method and apparatus to adjust voltage for storage location reliability." This invention involves an integrated circuit, such as a processor, that includes a counter to track the number of unreliable storage locations in the processor cache. It also features a detector to measure the thermal environment of the processor. If the actual number of unreliable storage locations exceeds an acceptable threshold, the circuitry raises the operating voltage of the processor, provided the thermal environment is suitable.
