Patent ID: 7224052

Claim:
An IC card comprising: a memory chip; a controller chip for controlling the memory chip; and a card substrate on which said memory chip and said controller chip are mounted, and having first connection terminals; and a detachable cover attached to the card substrate, wherein the first connection terminals are connected to a first group of external terminals of the controller chip, wherein external terminals of the memory chip are connected to a second group of external terminals of the controller chip, wherein second connection terminals connected to the second group of external terminals of the controller chip are formed on the card substrate, wherein said cover is configured such that, said first connection terminals are exposed to outside of the IC card, and said external terminals of the memory chip, said second group of external terminals of the controller chip and said second connection terminals are covered and inaccessible from outside the IC card, and wherein the second connection terminals are arranged to provide access to the memory chip independently of control of the memory chip by the controller chip, when said cover is detached from the card substrate.
