Patent ID: 6922343

Claim:
A memory card, comprising: a main body in which a recessed notch is formed on a side surface of its planar shape situated between a too surface and a bottom surface of said main body; a semiconductor memory in which data can be at least written, the semiconductor memory being mounted on a substrate contained inside the main body; a terminal provided in the main body of the memory card for electrically connecting the semiconductor memory to an external device; and a write/nonwrite setting element slidably fitted in the main body at the recessed notch for setting a write/nonwrite state of the data in the semiconductor memory by selection of any of a first position, where a portion of the write/nonwrite setting element covers a portion of the recessed notch, and a second position, where the portion of the write/nonwrite setting element covers another portion of the recessed notch, a path extending through said notch from above said top surface to below said bottom surface; wherein the write/nonwrite setting element and the recessed notch form an indicator of the setting status of the write/nonwrite state of data in the semiconductor memory.
