    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: 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 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: When underflow of a sub-Q data table occurs, a sub-Q data processing section does not read and output sub-Q data but outputs only audio data. Moreover, to achieve consistency between audio data and the sub-Q data in terms of buffer management, an input processing section includes respective counters for managing respective input data amounts of the audio data and the sub-Q data. Then, the input processing section executes management so that overflow and underflow of the sub-Q data table are suppressed as much as possible and a switch changes an IEC output mode at a time of audio processing and a time of dubbing. Thus, sound deterioration, and error recording in equipment to which the audio player is connected, and the like can be prevented.
