FLIP-FLOP HAVING LOGIC STATE RETENTION DURING A POWER DOWN MODE AND METHOD THEREFOR

摘要

A flip-flop includes a master latch, a first inverter, a slave latch, and a first clocked inverter. The master latch has an input for receiving an input signal and an output. The first inverter has an input coupled to the output of the master latch and an output for providing an output of the flip-flop. The slave latch is directly connected to the input of the first inverter. The first clocked inverter has an input directly connected to the slave latch and an output coupled to the master latch.
