Claim:
1. A differential amplification circuit comprising: a differential amplification unit including a first input transistor and a second input transistor, and suitable for differentially amplifying input signals inputted through the first and second input transistors; a first input control section suitable for turning off the first input transistor when the differential amplification circuit is disabled and transferring a first input signal to the first input transistor when the differential amplification circuit is enabled; and a second input control section suitable for turning off the second input transistor when the differential amplification circuit is disabled and transferring a second input signal to the second input transistor when the differential amplification circuit is enabled, wherein the differential amplifier unit further comprises: two cross-coupled inverters suitable for differentially amplifying the signals inputted through the first and second input transistors.
