    • In order to protect the user security data, provided is a memory card capable of preventing the data leakage to a third party not having the access authority by imposing the limitation on the number of password authentications and automatically erasing the data. In a system comprised of a multimedia card and a host machine electrically connected to the multimedia card and controlling the operations of the multimedia card, a retry counter for storing the number of password authentication failures is provided and the upper limit of the number of failures is registered in a register. When passwords are repeatedly entered once, twice, . . . and n times and the retry counter which counts the entries reaches the upper limit of the number of failures, the data is automatically erased so as not to leave the data in the flash memory.

    • 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.

    • A memory card is provided in which power consumption is reduced by the pull-up resistor of an input terminal and a misoperation induced by the pull-down resistor of a host apparatus is prevented. The memory card has a select terminal connected to the pull-up resistor. When the mode of the memory card is determined based on an input from the select terminal, a relatively low resistance value is selected for the pull-up resistor of the select terminal before a determination timing and the pull-up resistor is restored to an initial resistance value after the mode determination. A relatively high resistance value reduces a leakage current consumed by the pull-up resistor of the select terminal. When a pull-down resistor is connected to the terminal of a memory card host to which the memory card is attached, if the resistance value of the pull-up resistor is excessively high, it is influenced by the drawing in of a current by the pull-down resistor. If the resistance value of the pull-up resistor of the select terminal is lowered at the time of mode determination, an adverse effect of the lowering of a potential by the pull-down resistor can be circumvented.
    • 提供了一种存储卡,其中通过输入端的上拉电阻降低功耗,并且防止由主机设备的下拉电阻引起的误操作。 存储卡具有连接到上拉电阻的选择端子。 当基于来自选择端子的输入确定存储卡的模式时,在确定定时之前为选择端的上拉电阻选择相对较低的电阻值,并且将上拉电阻恢复到初始值 模式确定后的电阻值。 相对较高的电阻值减小了选择端子的上拉电阻消耗的漏电流。 当下拉电阻连接到与存储卡相连的存储卡主机的端子时,如果上拉电阻的电阻值过高,则会受到电流的影响 下拉电阻。 如果选择端子的上拉电阻的电阻值在模式确定时降低,则可以避免下拉电阻降低电位的不利影响。
