Title: Innovations of Marcus Lathan Kornegay

Introduction

Marcus Lathan Kornegay is a prominent inventor based in Durham, NC (US). He has made significant contributions to the field of technology, particularly in data caching systems. With a total of 15 patents to his name, Kornegay's work has had a substantial impact on the efficiency of data processing.

Latest Patents

Among his latest patents is the "Write-back coherency data cache for resolving read/write conflicts." This invention involves a write-back coherency data cache that temporarily holds cache lines. It determines whether a copy of the requested data is cached in a write-back cache located in memory controller hardware. The cache holds data being written back to main memory for a period before the data is actually written. If the data is found in the write-back cache, it is removed and forwarded to the requesting processor, while the cache coherency state is updated accordingly.

Another notable patent is the "Dynamic initial cache line coherency state assignment in multi-processor systems." This invention provides a method, system, and computer program product for delivering lines of data from shared resources to caching agents. It involves receiving a request from a caching agent for a line of data, assigning an initial coherency state for that line, and then providing the line of data to the caching agent in the assigned state.
