D-Latch is a simple clocked memory element in which the output is equal to the stored state inside the element. In D-Latch the state is changed whenever the appropriate inputs change and the clock is asserted. A D-Latch has two inputs and two outputs. The inputs are the data value to be stored and a clock signal that indicates when the latch should read the value on the data input and store it. The outputs are simply the value of the internal state and its complement. When the clock input is asserted, the latch is said to be open, and the value of the output becomes the value of the data input. When the clock input is de-asserted, the latch is said to be closed, and the value of the output is whatever value was stored the last time the latch was open. What is the difference between DFF and D-Latch? Can one chip be used for constructing the other? Explain.
