ABSTRACT:
A bistable flip-flop with reset control is provided. The flip-flop includes a storage cell having a first inverter whose input can receive a write signal from an input signal delivered to the input terminal of the first inverter, and a second inverter which is feedback-mounted with respect to the first inverter. The flip-flop also includes a first switch controlled by a reset signal for enforcing a specified logic state at the input of the first inverter when the reset signal is active, and a second switch controlled by the reset signal so as to prevent the first inverter from receiving a write signal in a logic state opposite to the specified state when the reset signal is active.
