Patent number: 9286206Abstract: According to one embodiment, a memory system includes nonvolatile memories each storing data and an address table for acquiring an address of the data, and a control unit which is configured to be capable of accessing the nonvolatile memories in parallel, and issues table read requests for reading the address tables and data read requests for reading the data to the nonvolatile memories in response to read commands from a host. When a table read request and a data read request are issued to a same nonvolatile memory, the control unit processes the data read request in priority to the table read request.Type: GrantFiled: December 17, 2013Date of Patent: March 15, 2016Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Satoshi Kaburaki, Atsushi Kunimatsu

Publication number: 20160041871Abstract: According to one embodiment, an information processing apparatus includes a host and a memory system. The memory system includes a nonvolatile memory. The host includes a volatile memory, a first host control unit, and a second host control unit. The volatile memory includes a first area to be used by the host and a second area as a cache memory to temporarily store data of the nonvolatile memory. The first host control unit computes a first code, and stores the first data and the first code in the second area. The first code is redundant information of the first data. The second host control unit reads second data and a second code from the second area, performs error detection on the second data based on the second code, and transfers the second data. The second code is redundant information of the second data.Type: ApplicationFiled: February 27, 2015Publication date: February 11, 2016Applicant: Kabushiki Kaisha ToshibaInventors: Kenichi MAEDA, Nobuhiro KONDO, Kenichiro YOSHII, Satoshi KABURAKI

Patent number: 8291193Abstract: An address translation apparatus includes first to third retention units, a comparison unit, and a translation unit. The first retention unit retains a multi-bit first address. The second retention unit retains a multi-bit second address different from the first address. The third retention unit retains first information indicating which bit is a translation target in the multi bits of the first address. The comparison unit compares a multi-bit third address input from outside and the first address. The translation unit translates the bit indicated by the first information in the multi bits of the third address to obtain a fourth address such that the bit indicated by the first information coincides with the second address, when the third address coincides with the first address based on comparison result of the comparison unit.Type: GrantFiled: April 17, 2008Date of Patent: October 16, 2012Assignee: Kabushiki Kaisha ToshibaInventor: Satoshi Kaburaki
