Abstract
A computer supplies an enable command and a password to a controller after a memory card is attached to the computer. The controller allows acceptance of an access command if the supplied enable command and password coincide with those stored in a flash memory, or refuses the acceptance of the access command if the supplied enable command and password differ from those stored in the flash memory. The controller updates the enable command and password if a password setting command and newly prepared enable command and password are supplied to the controller from the computer during access command accept mode. The controller refuses the access command if the computer supplies to the controller a correct enable command but a wrong password during the access command accept mode.
