20090100290 | MEMORY CONTROLLER, NONVOLATILE MEMORY DEVICE, NONVOLATILE MEMORY SYSTEM, AND DATA WRITING METHOD - A nonvolatile memory device comprises a nonvolatile memory and a memory controller. The nonvolatile memory includes the same memory cells striding over a plurality of pages. A page information instruction part has the page structure information of the nonvolatile memory. According to this information, a related page identification part identifies a page (related page) in which the data may change. The relation data stored in the related page are temporarily stored into a save memory before an error occurs, and if an error exists, these relation data are used to repair the data that have changed. By this method, in a memory device using a nonvolatile memory including the same memory cells striding over a plurality of pages, even if an error occurs during data writing, the error is repaired and the reliability can be ensured. | 04-16-2009 |
20090210621 | NONVOLATILE MEMORY DEVICE, NONVOLATILE MEMORY SYSTEM, AND ACCESS DEVICE - Power consumption required for making a nonvolatile storage device having a radio communication function operate as a file server for a radio host device is great for a host device which supplies the power. The present invention enables a user to operate a host device to which the nonvolatile storage device having the radio communication function is attached so as to activate and inactivate the radio communication function of the nonvolatile storage device. This reduces unnecessary power consumption by the radio communication function. | 08-20-2009 |
20090277965 | SEMICONDUCTOR MEMORY CARD - A semiconductor memory card is provided with a transmitting and receiving circuit of a plurality of transmission systems such as a single-end signaling transmitting and receiving unit and a differential signaling transmitting and receiving unit. When power is turned on, each transmitting and receiving unit is turned on. When a command is provided from a host device, a command processing unit judges the transmission system provided in the host device, based on reception results of each circuit. Then, only a transmitting and receiving unit of the system identical to the transmission system used for transmission is turned on, and the subsequent data transmission is performed. Thus, the semiconductor memory card provided with a plurality of transmission systems performs transmission by simply identifying the transmission system provided in the host device. | 11-12-2009 |
20100023678 | NONVOLATILE MEMORY DEVICE, NONVOLATILE MEMORY SYSTEM, AND ACCESS DEVICE - When an access device accesses a nonvolatile memory device, the nonvolatile memory device or the access device detects or calculates a temperature T of the nonvolatile memory device. A temperature-adaptive control part of the nonvolatile memory device controls an access rate to a nonvolatile memory on the basis of the temperature T. Accordingly, the control part controls the rate so that the temperature T of the nonvolatile memory devices cannot exceed a limit temperature Trisk. In this manner, a nonvolatile memory system can eliminate a risk of a burn when ejecting the semiconductor memory device and can read and write data at a high speed. | 01-28-2010 |
20100058074 | RIGHT INFORMATION ENCRYPTION MODULE, NONVOLATILE MEMORY DEVICE, RIGHT INFORMATION RECORDING SYSTEM, RIGHT INFORMATION DECRYPTION MODULE, RIGHT INFORMATION READING SYSTEM, AND RIGHT INFORMATION RECORDING/READING SYSTEM - A right information encryption module | 03-04-2010 |
20100318760 | MEMORY CONTROLLER, NONVOLATILE STORAGE DEVICE, AND NONVOLATILE STORAGE SYSTEM - A method for use in a nonvolatile storage device that can resize one or more partitions prevents an address management table from becoming complicated after repeated resizing of partitions. When a partition is resized, a logical-to-physical conversion table is updated by shifting a physical block address corresponding to a partition subsequent to the resized partition by the resized amount of the partition. The method enables both logical addresses corresponding to partitions and logical addresses not corresponding to partitions to be constantly continuous to one another. | 12-16-2010 |
20110242362 | TERMINAL DEVICE - In the case where a plurality of types of attribute information and a plurality of types of menu screen information of different formats are recorded on a nonvolatile recording medium by a plurality of types of terminal devices, the display device cannot determine which information is to be processed. This makes it difficult for the user to view images or the like. A terminal device | 10-06-2011 |
