Latest Patents

Among his latest patents, one includes an "Arrangement of data within cache lines so that tags are first data received." This invention focuses on a memory system and method for processing a data structure that comprises a plurality of data bits representing a line of memory. The data bits are divided into several data chunks, each containing an error correction code portion and a data portion. Notably, the first chunk includes a tag portion that contains tag information for the entire line of memory, while subsequent chunks do not include tag information. Another significant patent is for a "Memory controller that provides memory line caching and memory transaction coherency by using at least one memory controller agent." This invention describes a memory controller that includes a memory-controller agent, an incoming memory-transaction dispatch unit, and an outgoing memory-transaction completion unit. The memory controller is designed to manage memory transactions efficiently, ensuring coherency and caching of memory lines.
