Abstract

PURPOSE:To prevent the relinquishment of information, to enable re-writing of information and to save energy by means of a solar battery, by using a rewritable non-voltatile storage element lucky electron injection type memory. CONSTITUTION:An information input is inputted to a small sized electronic device through a switch circuit 1. An output of the circuit 1 is processed at a signal processing circuit 2, and information exchange is made between the circuit 2 and a storage circuit 3 as required, and the result is displayed on a display circuit 4. This device is provided with a solar cell 5 and the power supply such as a silver cell can be used at the same time. The relinquishment of information is prevented by using a lucky electron injection type memory newly developed, the rewriting of information is made possible, and the solar energy can effectively be used with the solar call.
