Abstract
A sense amplifier circuit includes an amplifier including first and second inverter circuits which each have a pair of thin film transistors and are connected in a cross-coupled configuration, a precharging thin film transistor connected between the first and second inverter circuits, input transfer gates respectively connected between the first and second inverter circuits and first and second input terminals, and output transfer gate respectively connected between the first and second inverter circuits and first and second input terminals. With the above construction, the precharging thin film transistor is made active to precharge the amplifier and then the transfer gates are operated to permit an input signal to be input to the amplifier, thereby causing the input signal to be discriminated between two values and amplified.
