摘要:
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.

A memory card, which is a storage device connectable to a terminal, includes a buffer memory in which externally-provided data is stored, a flash memory, and a controller which controls reading and writing of data from and to these memories. The controller saves a divided input data in the non-volatile memory in accordance with a result of determination regarding data size information contained in a first divided input data of data externally inputted for a security process and a data management size of the storage device, and the controller reads the saved data to the memory for performing the security process when it receives an n-th divided input data.

In technology for enabling the replacement of part of an operating program of a controller by a modified program on a nonvolatile memory, the present invention prevents tampering and leak of storage information within the nonvolatile memory and the controller. At power-on reset, an encrypted alternative program, if present, is transferred from a nonvolatile memory to a volatile memory, and decrypted when actually executed. A long wait is not required until data processing by a data processor is enabled after the exit from the reset processing. Since the alternative program once decrypted is held in the volatile memory so as to be reusable, it does not need to be decrypted each time it is executed. Since the alternative program is encrypted, even if the nonvolatile memory is physically separated from the controller to illegally dump the alternative program, it is difficult to analyze the data.
摘要:
The invention intends to provide a memory card conforming to an HS-MMC mode in a standard of a multimedia card, while securing compatibility of both standards of the multimedia card and an SD card. In a normal MMC mode, the data is outputted at a fall edge of a clock signal. A frequency of the clock signal is about 20 MHz. When the data is outputted at the fall edge of the clock signal, data output is in time for a next clock signal. When a parameter ‘1’ is set to a timing register provided in a host interface, the memory card is transitioned into the HS-MMC mode. In the HS-MMC mode, a clock signal frequency is increased to about 52 MHz. Here, the data is outputted at the rise edge of the clock signal, whereby the data output is brought in time for the rise edge of the next clock signal.
