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.
