Provided are a latch and a D trigger. The latch comprises: a switch, a variable resistance-type memory, a voltage-dividing circuit and a voltage converter. When the switch is in a turned on state, the voltage converter is used for outputting an output signal of the latch according to an input signal of the latch, the output signal remaining consistent with the input signal. When the switch changes from the turned on state to a turned off state, the variable resistance-type memory is used for coordinating with the voltage-dividing circuit to enable the output signal of the latch when the switch is in the turned off state to remain consistent with the output signal of the latch when the switch is in the turned on state, thereby implementing a non-volatile latching function. Since the latch in the present invention uses relatively few components, circuit structure in simple, circuit area is reduced, and the level of integration of existing logic circuits can be improved. |
