摘要: In the initial setting of a memory card 1, the flash check data FD stored in a flash memory 2 is read out, this data FD is compared with the operation check data FD11 stored previously in the ROM, the write check data FD12 stored in the ROM 4a is written, if a fault is not detected, to the flash memory 2, and this data is read again and is compared with the write check data. FD12 of the ROM 4a. When any fault is not detected in comparison of these data, the CPU determines that the flash memory 2 is normal. Moreover, if a fault is detected in the comparison of data, the CPU sets the reset process fault data to a register 5a to set a controller 3 to the sleep mode. When the command CMD is received during this period, data comparison is executed again.

摘要: A memory card is provided with a transfer control circuit, a write control circuit and a judging circuit. The transfer control circuit outputs a transfer flag signal during the data transfer. The write control circuit outputs an internal busy signal during the data write operation. The judging circuit outputs a transfer interruption signal when a card selection signal of the host is negated during the input of the transfer flat signal and also outputs a suspension signal when the card selection signal is negated during the input of the internal busy signal. A CPU invalidates the data being transfer to interrupt the transfer process upon reception of the transfer interruption signal and completes, upon reception of the suspension signal, the process being executed and stays in the waiting condition. Consequently, even when the timing signal not conforming to the standards is transferred, the host can select the optimum processing operation from the internal processing conditions and thereby execute the selected operation.

摘要: When a non-volatile memory write error occurs in a card storage device containing a non-volatile memory and an error correction circuit, write data is read from the non-volatile memory and a check is made if the error can be corrected by the error correction circuit. If the error can be corrected, the write operation is ended. If the error correction circuit cannot correct the error, substitute processing is performed to write data into some other area.
