Abstract
A master latch implemented to receive feedback from a slave latch on a different input terminal than a input terminal on which data bits are received. Due to such receiving, the number of transistors/area and/or power consumption requirements (efficiently) may be minimized in implementing a flip-flop. The feedback path may be implemented using a single pass-gate, further enhancing the efficiency of implementation. In addition, clock enable/disable signals may be generated efficiently taking into account an externally received flip-flop disable signal and absence of transitions in the data input bits. When the flip-flop is implemented to support ATPG type sequential scanning testing, a multiplexor may be implemented efficiently to select either the data bits or scan bits.
