Abstract

PURPOSE:To prevent the destruction of an information write circuit by controlling an inverter, which is dependent upon conductive-type depletion and enhancement- type FETs, through a CMOS transistor. CONSTITUTION:When bus line 6 of inverter 12 of a CMOS transistor formed by P and N-type FETs 10 and 11 becomes a low level by an address signal, FETs 10 and 11 are turned on and off respectively to break P enhancement FET 13 constituting inverter 15, and P depletion FET 14 where bus line 6 is connected becomes conductive, and the potential of inverter 15 becomes equal to the potential of low-potential power source VSS. When a low-potential write signal is applied to the drain of PMOSFET 18 through write control circuit 16, a negative high voltage is generated on write bus line 8 through FET 18 which becomes conductive by capacitor 19, and information to a memory element is transferred without applying the high voltage to the CMOS transistor, so that the destruction of the CMOS transistor of a write logical operation circuit can be prevented. Further, the write at a high voltage brings the same result by a similar circuit.
