When the enable input is made low (0), the latch ignores the status of the D input and merrily holds the stored bit value, outputting at the stored value at Q, and its inverse on output not-Q. The circuit uses two NOR gates to create an SR latch that turns on and off an LED with separate. You can write (store) a 0 or 1 bit in this latch circuit by making the enable input high (1) and setting D to whatever you want the stored bit to be. Contents may have variations from the printed book or be incomplete or contain other coding. The CD4001 is a CMOS chip with four 2-input NOR gates.

The J-K Flip-flop is constructed with NAND and inverted-OR gates. NAND gates are used to design a wide range of logic functions, including SR Latches and D Flip-Flops.
