| 20100169556 | NONVOLATILE STORAGE DEVICE, INFORMATION RECORDING SYSTEM, AND INFORMATION RECORDING METHOD - A nonvolatile storage device includes a nonvolatile memory configured to store user data and management information used to manage the user data on a file system, and a medium controller configured to determine whether a command input from a host device is used for the user data or the management information, the command describing content of processing performed for the user data or the management information, and switch between control methods used for the nonvolatile memory on the basis of the determination result. | 07-01-2010 |
| 20100287332 | DATA STORING SYSTEM, DATA STORING METHOD, EXECUTING DEVICE, CONTROL METHOD THEREOF, CONTROL DEVICE, AND CONTROL METHOD THEREOF - A data storing system including: a non-volatile memory configured to have a plurality of memory blocks each capable of independently operating and allow random access to each of addresses; a controller configured to control writing of data to the non-volatile memory; and an executing unit configured to execute a predetermined application, wherein the executing unit decides the number of interleaves indicating the number of memory blocks operated in parallel among the plurality of memory blocks, and the executing unit notifies the controller of the decided number of interleaves. | 11-11-2010 |
| 20110010580 | Memory apparatus, memory controlling method and program - A memory apparatus includes a memory having a main memory area and a replacement area, and a memory controller having a function of issuing instructions corresponding to commands to carry out transmission and reception of data and reading of status information of the memory. | 01-13-2011 |
| 20110035646 | NONVOLATILE RANDOM ACCESS MEMORY AND NONVOLATILE MEMORY SYSTEM - A nonvolatile random access memory includes: a nonvolatile storage area that is randomly accessible and includes a data area to store data and an error-correcting-code area to store an error correcting code, the data area including at least one data area to which a data area unit size is assigned, the error-correcting-code area including at least one error-correcting-code area to which an error-correcting-code-area unit size is assigned; and a nonvolatile storage area controller to set a data size used when the at least one data area is accessed, as the data area unit size. The nonvolatile storage area controller manages the data area and the error-correcting-code area based on the set data area unit size and assigns the at least one error-correcting-code area with the error-correcting-code-area unit size to the at least one data area with the data area unit size based on the data area unit size. | 02-10-2011 |
| 20110066923 | NONVOLATILE MEMORY APPARATUS, MEMORY CONTROLLER, AND MEMORY SYSTEM - Disclosed herein is a nonvolatile memory apparatus including, a nonvolatile memory section, a standard error correction code processing section, an extended error correction code processing section, and a control section. | 03-17-2011 |
| 20110087836 | STORAGE UNIT AND MEMORY SYSTEM - A storage unit includes: a random access memory device and a storage device to be accessed using an address in units of word and sector, respectively; and a storage controller controlling accesses to the random access memory device and the storage device according to the addresses designated via a bus. The storage controller includes first and second interface functions for access to data stored on the storage device and the random access memory designated using the sector address and the word address provided via the bus, respectively, a function of using the random access memory device as a first disk cache and determining data to be saved in the random access memory device in response to the access by the first interface function, and functions of transferring the data designated using the sector address by repeating register access and by a bus master function as continuous word-sized data through the bus. | 04-14-2011 |
| 20110119558 | NONVOLATILE MEMORY AND MEMORY SYSTEM - Disclosed herein is a nonvolatile memory, including: a memory area including a data area configured to retain data and an error correction code area configured to retain an error correction code known as ECC; and a control unit configured to control access to the memory area. The control unit includes an error detection and correction function configured to detect an error in the data read from the data area and to correct the detected error, at least one save area configured such that if data at a designated address and ECC corresponding thereto are read from the memory area and if an error is detected, then the save area retaining the address and correct data corresponding thereto, and a validity presentation block configured to indicate whether or not the address and the correct data retained in the save area are valid. | 05-19-2011 |
