1. An IC module comprising:
- a non-volatile memory chip;
a controller chip for controlling the non-volatile memory chip;
an interface for contact communication; and
an interface for contactless communication, wherein the controller chip can authenticate a user of a host equipment, wherein the controller chip executes a processing of data transmitted through the interface for contactless communication using power supplied from the host equipment to the interface for contact communication, wherein the processing of data includes an operation of reading the data from the non-volatile memory chip by the controller chip and an operation of writing the data in the non-volatile memory chip by the controller chip, and wherein the controller chip executes initialization of the non-volatile memory chip between an activation of the host equipment and a completion of the authentication of the user indicated by the host equipment.

Abstract
In a SIM card having a flash memory chip, a memory controller chip, and contact/contactless card interfaces, the memory controller chip has a function of executing user authentication of a host equipment, executes processing of data transmitted through the contactless IC card interface (executing reading or writing of data to the flash memory chip) using power supplied from the host equipment to the contact IC card interface, and executes initialization of the flash memory chip between activation of the host equipment and completion of user authentication instructed by the host equipment.
