MEMORY CARD AND SEMICONDUCTOR DEVICE
First Claim
1. A memory card, comprising:
- a nonvolatile memory;
a card controller that reads and stores data from and in said nonvolatile memory; and
an IC card microcomputer that performs cryptographic processing,wherein a pin column is formed along one side of said memory card,wherein said pin column has two potential supply pins, a data pin, a clock pin, and two antenna connecting pins,wherein said two antenna connecting pins are divided into two areas in which a size of said one potential supply pin is the largest and used as a split pin arranged at intervals, andwherein said IC card microcomputer inputs and outputs data via an antenna connected to said antenna connecting pin.

Abstract
An antenna connection function for a noncontact interface is provided by suppressing a modification in a pin arrangement and a pin shape of a memory card that does not correspond to the noncontact interface. Two antenna connecting pins having the memory card are divided into two areas in which a size of one potential supply pin is the largest and used as a split pin arranged at intervals. Because a size of the two antenna connecting pins is at maximum as large as the size of the potential supply pin, the two antenna connecting pins are provided and the memory card that corresponds to the noncontact interface is obtained by devoting a pin area having the size of the one potential supply pin to the memory card that does not correspond to the noncontact interface. Accordingly, the pin area of the memory card that corresponds to the noncontact interface can be formed without departing from the pin area of the memory card that does not correspond to the noncontact interface.
