Abstract: In an embodiment of the invention, a flip-flop circuit contains a 2-input multiplexer, a master latch, a transfer gate and a slave latch. The scan enable control signals SE and SEN of the multiplexer determine whether data or scan data is input to the master latch. The clock signals CLK and CLKN and retention control signals RET and RETN determine when the master latch is latched. The slave latch is configured to receive the output of the master latch, a second data bit D2, the clock signals CLK and CLN, the retain control signals RET and RETN, the slave control signals SS and SSN. The signals CLK, CLKN, RET, RETN, SS and SSN determine whether the output of the master latch or the second data bit D2 is latched in the slave latch. Control signals RET and RETN determine when data is stored in the slave latch during retention mode.

Abstract: In an embodiment of the invention, a dual-port positive level sensitive reset data retention latch contains a clocked inverter and a dual-port latch. Data is clocked through the clocked inverter when clock signal CKT goes high, CLKZ goes low, reset control signal REN is high and retention control signal RET is low. The dual-port latch is configured to receive the output of the clocked inverter, a second data bit D2, the clock signals CKT and CLN, the retain control signals RET, the reset control signal REN and the control signals SS and SSN. The signals CKT, CLKZ, RET, REN, SS and SSN determine whether the output of the clocked inverter or the second data bit D2 is latched in the dual-port latch. Control signal RET determines when data is stored in the dual-port latch during retention mode.
