Title: Innovations by Javier Villagomez

Introduction

Javier Villagomez is an accomplished inventor based in San Jose, CA. He has made significant contributions to the field of cache memory architecture, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is titled "Low-power cache system and method." This invention provides a cache architecture that selectively powers up a portion of the data array in a pipelined cache architecture. A tag array is first powered up, while the data array remains off, allowing for the determination of a tag hit from the decoded index address. If a tag hit occurs, the data array is powered up to enable the corresponding cache line for placement onto a data bus. This method conserves significant power during the assessment phase, as the tag consumes only a fraction of the power used by the data array.

Another notable patent is "Scalable replacement method and system in a cache memory." This invention outlines a system and method for executing a replacement selection algorithm embedded in each associativity of a cache memory architecture. Each associativity has internal control logic that governs the replacement process when certain conditions, such as a TagHit, occur. The preferred replacement algorithm utilizes an approximation to Not the Most Recently Used Associativity (NMRU), enhancing the efficiency of cache memory management.
