Abstract

PURPOSE:To write information at a high speed and to make it npn-volatile, by inputting 2 kinds of pulses to the gate of an MNOS transistor. CONSTITUTION:Negative voltage is applied to N-MNOS transistors (TRs) TR 15, 16 from a pulse voltage signal line (MG line). As a result, the Trs 15 and 16 become a depression type, both the transistors operate in the same way as an electric conductor of low resistance, and a memory cell operates in the same way as a static RAM constituted of a conventional C-MOS. That is to say, the information is written at a high speed. Subsequently, when a positive pulse is applied to both the gates of the TRs 15 and 16, the TR15 is in a state of a depression type, and on the other hand, the TR16 becomes an enhancement type from the depression type. In this way, even if supply voltage Vcc is turned off, the written information is not varied unless an erase pulse is applied from the MG line once again.
