摘要
A flag holding circuit includes: a flag setting part connected to a voltage supply line and charging a capacitor according to an input signal; a flag determination part outputting an output signal based on a charging voltage of the capacitor; and a discharging part discharging the capacitor. The flag setting part includes: a switch having a first terminal connected to a connection line between the flag determination part and the discharging part and a second terminal connected to the voltage supply line or a grounding line according to a signal level of the input signal, and connecting or disconnecting the voltage supply line or the grounding line with the connection line according to a leakage control signal; and a switch control part, generating the leakage control signal whose signal level changes to be greater than a power supply voltage according to a clock signal and supplying it to the switch.
