Mitsubishi Electric Assigned Patent

Mitsubishi Electric Corporation, Tokyo, Japan, has been assigned a patent (9,170,929) developed by Kikkawa, Koji, and Nakata, Masanori, Tokyo, Japan, for a “memory controller.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A data storage temporarily stores an address conversion table associating the sector numbers with the physical addresses for each file. A conversion table memory allocator allocates a memory region for the address conversion table corresponding to a file when a request is made to open the file. A file system manager releases the allocated memory region at a given time. The file system manager stores sector numbers of one or multiple sectors constituting a file in each record of the address conversion table for which the memory region is allocated in sequence. Then, a memory control section searches the flash memory to acquire a physical address corresponding to a sector number in the each record of the address conversion table, and stores each acquired physical address in the corresponding record.“

The patent application was filed on January 31, 2011 (13/982,409).
