Patent number: 8051331Abstract: 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.Type: GrantFiled: March 26, 2009Date of Patent: November 1, 2011Assignees: Renesas Electronics Corporation, Hitachi ULSI Systems Co., Ltd.Inventors: Hidefumi Oodate, Atsushi Shiraishi, Shigeo Kurakata, Kunihiro Katayama, Motoki Kanamori

Patent number: 7343445Abstract: 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.Type: GrantFiled: October 3, 2006Date of Patent: March 11, 2008Assignees: Renesas Technology Corp., Hitachi ULSI Systems Co., Ltd.Inventors: Kunihiro Katayama, Motoki Kanamori, Atsushi Shikata, Hidefumi Oodate, Atsushi Shiraishi
