ABSTRACT:
Versatility of a memory card is improved by providing a memory card where data protection mode and normal mode can be selected at discretion. A portable auxiliary storage device includes a mode setting section, a mode detecting section and a memory access control section. The mode setting section allows a user to set a normal mode permitting reading data stored in a memory section or writing the data to the memory section without restriction and a data protection mode for restricting the reading or writing. The mode detecting section detects a mode set in the mode setting section. The memory access control section controls the read or write according to a state of the mode setting section detected by the mode detecting section.
