Latest Patents

Furuya's latest patents include a cache system used in a magnetic disk controller that adopts an LRU (Least Recently Used) system. This invention features a magnetic disk controller incorporating a cache memory that employs an LRU scheme in the replacement algorithm of cache blocks. It comprises a directory memory with entries that have LRU counter fields, a host system issuing read/write commands with an arbitrary LRU settling value, a directory search circuit, and a microprocessor. The directory search circuit is designed to search the directory memory in response to the read/write command issued from the host system. The microprocessor plays a crucial role by storing the LRU setting value appended to the read/write command in the LRU counter field of the hit entry of the directory memory or the entry corresponding to the replacement target cache block, based on the search result of the directory search circuit.
