    摘要： The invention is directed to largely improve reliability by surely protecting data on the basis of an emergency stop request even during a data transfer process. The invention provides a data memory system taking the form of a memory card or the like. When an emergency stop signal requesting an emergency stop is received from an information processor of a host during a read/write data transfer process, a control circuit immediately stops the transfer process and notifies the information processor of end of the read data transfer. At this time, the end of read data transfer is notified irrespective of whether the transfer is finished normally or abnormally. Even when a read data transfer request is received again from the information processor after notifying the information processor of the end of read data transfer, without transferring data, a controller notifies the information processor of an untransferable state of read data.

    摘要翻译： 本发明旨在通过在数据传送过程中即使基于紧急停止请求来确保数据的保护来大大提高可靠性。 本发明提供一种采用存储卡等形式的数据存储系统。 在读/写数据传送处理期间，当从主机的信息处理器接收到请求紧急停止的紧急停止信号时，控制电路立即停止传送处理，并向信息处理器通知读取的数据传送结束。 此时，无论传输是正常还是异常地完成，都会通知读取数据传输的结束。 即使当在通知信息处理器之后再次从信息处理器接收到读取数据传送的结束而不传送数据时，控制器向信息处理器通知读取数据的不可转移的状态。

    摘要： To prevent stored information from being changed even at the occurrence of an abnormal condition in an upstream side of a system due to uncontrollable run of an OS. A nonvolatile storage means having data storage areas and management areas for them in units of predetermined physical addresses has an access protect definition table TLB in a predetermined physical address, and the table has access attribute information defining whether to permit or not access to the data storage areas in association with the physical addresses. The memory system itself possesses access attribute information defining whether to permit or not a write to and a read from the data storage areas in association with addresses to implement an access protect function for write and read. Therefore, the access protect function is maintained even if an abnormal condition occurs in a host device that manages the memory system or controls it as a peripheral circuit.

    摘要： It is aimed to detect, notify, and save an abnormal area in semiconductor memory for greatly improving reliability. An inside of semiconductor memories provided for a memory card comprises a user area, a substitution area, an area substitution information storage area, and a management area. An inside of semiconductor memories comprises a user area, a substitution area, and a management area. The user area is a data area a user can use. The substitution area is substituted when an error occurs in the user area. The area substitution information storage area stores area substitution area information. The management area stores substitution information. The information processing section performs substitution on two levels as follows. When detecting an operation indicating a symptom of failure in a semiconductor memory area, the information processing section performs area substitution during an idle state of the memory card. When detecting a faulty operation in an area, the information processing section immediately performs area substitution.

    摘要： The present invention provides a memory device that can flexibly decide the data to be preread. The memory device according to the present invention includes: a nonvolatile memory; a buffer memory having a higher access speed than the nonvolatile memory; and a control circuit. The control circuit creates a preread data management table that associates a logical address of preread data specified by a preread command inputted from the outside and a buffer memory address for storing the preread data. Moreover, the control circuit reads data specified by the command from the nonvolatile memory and stores it in the buffer memory as preread data. When a logical address specified in a read command inputted from the outside matches a logical address associated by the preread data management table, the control circuit outputs corresponding preread data from the buffer memory.

    摘要： A memory system permitting a number of alternative memory blocks to be made ready in order to extend the rewritable life and thereby contributing to enhanced reliability of information storage is to be provided. The memory system is provided with a nonvolatile memory having a plurality of data blocks in predetermined physical address units and a controller for controlling the nonvolatile memory in response to an access request from outside. Each of the data blocks has areas for holding a rewrite count and error check information regarding each data area. The controller, in a read operation on the nonvolatile memory, checks for any error in the area subject to the read according to error check information and, when there is any error, if the rewrite count is greater than a predetermined value, will replace the pertinent data block with another data block or if it is not greater, correct data in the data block pertaining to the error.

    摘要： A memory card includes a non-volatile memory, a memory controller for controlling the operation of the memory card. The memory controller is capable of providing an interface with outside according to a predetermined protocol, and performs error detection and correction of the memory information at regular time intervals or at the timing of connection of electric power supply, independently of reading out the memory information according to external access request. Therefore, it is possible to improve reliability of data retention in the non-volatile memory without the host device reading out the memory information from the non-volatile memory of the memory card.
