ABSTRACT:
A semiconductor integrated circuit comprises: a latch circuit constituted with a drive inverter and a feedback inverter so as to be connected in a cyclic form, wherein at least one of the drive inverter and the feedback inverter comprises a MOS transistor; anda current source connected to at least one of latch nodes of the latch unit. The magnitude relation of electric current flown in the MOS transistor and electric current flown in the current source is judged based on presence or absence of inversions in data values latched in the latch node.
