Patent ID: 7044389

Claim:
A non-volatile memory apparatus comprising: first external terminals which include a command terminal for receiving operating commands and a data terminal for receiving or providing data; second external terminals; third external terminals; a memory card function block which includes a controller coupled to the first and the third external terminals and an electrically erasable and programmable non-volatile memory coupled to the controller; and an IC card function block which is coupled to the second and the third external terminals and includes a microprocessor operative to perform a security function, wherein said first external terminals are dedicated to said memory card function block, wherein said second external terminals include a terminal which is used for data inputting to or data outputting from said IC card function block, and which is used only for said IC card function block, and wherein said controller of said memory card function block is structured on one semiconductor substrate and said microprocessor of said IC card function block is structured on one semiconductor substrate different from the one semiconductor substrate on which said controller is structured.
