FLIP-FLOP CIRCUIT OF HAVING MULTI-THRESHOLD VOLTAGE CMOS AND METHOD OF DRIVING THE SAME

摘要

PURPOSE: A flip-flop circuit of having a multi-threshold voltage CMOS and a method of driving the same are provided to implement high speed operation in an active mode while minimizing power consumption in a sleep mode. CONSTITUTION: A first latch unit(500) updates an output signal according to the level of a second node or maintains the output signal. A second latch unit(600) updates the reversed output signal according to the level of the third node and maintains the reversed output signal. A data recovery unit(300) recovers the output signal of a first and second output node of a sensing amplifier before entering an active mode.
