Information storage and information processing system utilizing state-designating member provided on supporting card surface which produces write-permitting or write-inhibiting signal

Abstract

In a small and thin memory module for sharing data among electronic devices such as information processing apparatuses, a write prohibit state can be visually recognized. A conductive seal is attached to a predetermined position on a support member, thereby setting the memory module in the write prohibit state. The conductive seal visually indicates the write prohibit state. When the memory module is mounted in a connector section of a card-shaped holder, connector pins are electrically connected to each other via the conductive seal. That, a write prohibit mechanism is realized at low cost.
