Abstract
An IC card module includes first external connecting terminals and second external connecting terminals both exposed to one surface of a card substrate, a microcomputer connected to the first external connecting terminals, a memory controller connected to the second external connecting terminals, and a volatile memory connected to the memory controller. The shape of the card substrate and the layout of the first external connecting terminals are based on a standard of plug-in UICC of ETSI TS 102 221 V4.4.0 (2001-10). The second external connecting terminals are disposed outside the minimum range of the terminal layout based on the standard for the first external connecting terminals. The first and second external connecting terminals include signal terminals electrically separated from one another.
