Document Type and Number:

Japanese Patent JP2004356870

Kind Code:

A

Abstract:

To realize a portable terminal which easily encrypts and holds data supplied from an external apparatus in a data writing procedure on the initiative of the external apparatus.

A memory controller 111 writes SO data received from an SO data reader-writer 100 in an EEPROM 13 according to a write address. A flag setting unit 112 sets up an encryption request flag 113 when the writing of the SO data ends.
