Patent number: 7483297Abstract: The present invention provides a nonvolatile memory card in which a program is added, modified, changed, or the like by selecting arbitrary firmware on a flash memory from a plurality of pieces of firmware on flash memories. In a memory card, in addition to a program stored in a built-in ROM, firmware on flash memories as programs for adding, changing, modifying, or the like of a function such as a patch program are stored. Firmware on a flash memory which is desired to be made valid is set in a parameter sector or the like and is loaded into an external RAM, and the CPU of a control logic executes a process.Type: GrantFiled: October 13, 2007Date of Patent: January 27, 2009Assignee: Renesas Technology Corp.Inventors: Makoto Mori, Seisuke Hirosawa, Atsushi Shikata

Publication number: 20030225962Abstract: The present invention provides a memory card realizing a simplified erasing process and shortened process time as a whole and capable of preventing an illegal access to the memory card discarded, and a system using the memory card. A system includes a flash memory card and a host device which is electrically connected to the flash memory card and controls the operation of the flash memory card. The system includes an erase command for executing an operation of erasing information in a data area in a flash memory and, in addition, a purge command for executing an operation of erasing all of information in the data area and a management information area in the flash memory. The purge command is issued by the host device to the flash memory card, thereby enabling the whole areas in the flash memory to be erased by the single issue of the purge command without issuing the erase command a plurality of times.Type: ApplicationFiled: May 12, 2003Publication date: December 4, 2003Applicants: Hitachi, Ltd., Hitachi ULSI Systems Co., Ltd.Inventor: Seisuke Hirosawa

Patent number: 6584014Abstract: A nonvolatile storage system includes a plurality of nonvolatile memories and a control unit. When having detected a write-in error that occurred at an operation-subject nonvolatile memory, the control unit can set inter-chip alternate information indicating that a storage region related to the write-in error has been replaced by a storage region of any other nonvolatile memory of the plurality of nonvolatile memories to the nonvolatile memory of the storage region related to this error, so that when having received the inter-chip alternate information from the operation-subject nonvolatile memory, the control unit can change the operation subject from the current operation-subject nonvolatile memory to any other nonvolatile memory indicated by this inter-chip alternate information. It is thus possible to rescue a write-in error which occurred at one nonvolatile memory by replacing it with any other chip.Type: GrantFiled: February 26, 2002Date of Patent: June 24, 2003Assignees: Hitachi, Ltd., Hitachi ULSI Systems Co., Ltd.Inventors: Seisuke Hirosawa, Masaki Shirai, Takeshi Suzuki, Katsumi Ouchi
