Filed: 1985-08-23
Abstract: PURPOSE:To avoid needless destruction of an element by a method wherein a bipolar transistor is connected in parallel between the writing input terminal and the ground potential of a destructive writing type memory element and the bias level of the base of the transistor is given by a built-in source voltage in a semiconductor integrated circuit device. CONSTITUTION:A p-n-p type bipolar transistor Q1, which is an amplifying element, is connected in parallel between a writing input terminal Pin and a ground potential GND of a memory element M in a semiconductor integrated circuit device IC. When the semiconductor integrated circuit device IC is in handling state, the base bias voltage Vb of the transistor Q1 is declined nearly to the ground potential by cutting off an internal source line L from an external source. In this state, the transistor Q1 becomes continuous if the potential of the writing input terminal Pin exceeds only the voltage between the base and the emitter and prevents the potential of the writing input terminal Pin from rising. With this constitution, needless destruction of the memory element M caused by static electricity can be completely avoided.
