摘要： PROBLEM TO BE SOLVED: To provide a storage device and a method having a prioritized erase function.SOLUTION: A storage memory comprises at least one flash unit, and each flash unit comprises a plurality of blocks. A controller is configured: to write data into the plurality of blocks; to designate erasure priority, which correlates with the erasure priority of the data, to each block; and when receiving an emergency erase command, to immediately erase the data in each block according to the erasure priority of each block. Preferably, the controller is configured to perform writing of the data into the plurality of blocks in an arbitrary order in a first flash unit. And the writing into the subsequent flash units is performed in correlation with the order in the first flash unit. Preferably, erasure comprises aborting erasure, before completing the erasure, for at least some of the plurality of blocks.

摘要： PROBLEM TO BE SOLVED: To protect an authentication token connected to a computer from being hijacked by a malicious program.SOLUTION: In order to authenticate a transaction between a host and a server, a token is connected to the host. The host receives an identification certificate of a user. The identification certificate is then verified by the token and/or the server. When the token detects an artificial specified operation, the token generates token authentication data, and the host transmits the token authentication data to the server. Upon receiving the authentication data, the server authenticates the transaction.

摘要： PROBLEM TO BE SOLVED: To provide a method for processing internal operation of a storage device by the storage device, and to provide the storage device using the same. SOLUTION: This method allows the storage device to autonomously (i.e., without intervention of a host device) determine whether an integral sequence of commands, which is related to one or more storage commands issued by the host device, is in a certain state (i.e., it is "active" or "inactive") or is transitioning from "active" state to "inactive" state or from "inactive" state to "active" state. Depending on the determined state or transition, the storage device determines whether to refrain from executing Extra-Sequence ("ESQ") operations and permit executing Intra-Sequence ("ISQ") operations, or vice versa.

摘要翻译：要解决的问题：提供一种用于处理存储装置的存储装置的内部操作的方法，并提供使用该方法的存储装置。解决方案：该方法允许存储设备自主地（即，在没有主机设备的干预的情况下）确定与主机设备发出的一个或多个存储命令相关的整体命令序列是否在一定程度上状态（即，它是“活动”或“不活动”）或正从“活动”状态转换到“非活动”状态或从“非活动”状态转换到“活动”状态。根据确定的状态或转换，存储设备确定是否禁止执行Extra-Sequence（“ESQ”）操作并允许执行Intra-Sequence（“ISQ”）操作，反之亦然。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method and device for maintaining data structures in accordance with the events of a nonvolatile memory system.SOLUTION: At least part of one or more management tables and a future information data structure are stored in a nonvolatile memory. The future information data structure contains records of events expected to occur subsequent to the storing of the future information data structure. When flash memory events occur, those events are handled in accordance with the future information data structure. When a memory system starts up (410), the management table(s) is/are retrieved (414) and the records of the future information data structure are compared with the table(s) state (418). The table(s) is/are updated in accordance with the future information data structure (438).

摘要： PROBLEM TO BE SOLVED: To provide a flash memory device configured to allow a cache read operation of preceding page data.SOLUTION: The flash memory device includes an array of memory cells for storing data pages, one or more buffers for retrieving the data pages, and a logic mechanism that, responsive to a plurality of commands, transfers the data pages between the buffers and a host. Each command subsequent to a first command instructs retrieval of a data page whose address either precedes or exceeds by more than 1, the address of the data page retrieved by the immediately preceding command, and at least one command does not explicitly specify the address of its retrieved data page. Another similar flash memory device uses two buffers to implement cache reads of data pages whose addresses are specified arbitrarily in the commands subsequent to the first command.

摘要： PROBLEM TO BE SOLVED: To provide a more efficient method of selecting a device identifier at a memory device interface.SOLUTION: The method includes: receiving an enumeration message via a host interface of a device operatively coupled to a host device as well as to one or more other devices; and identifying the enumeration message as a command originated by the host device or as a response message from one of the other devices. The method includes, in response to identifying the enumeration message as a command, selectively sending an enumeration response message to the host device. The enumeration response message indicates a distinctive device identifier value. The method also includes reading from a response message an identifier value used by such other device and at least temporarily storing this identifier value at the device to enable the device to select the distinctive device identifier value.
