2. Summary

3. NAND-gate Latch The time sequence at right shows the conditions under which the set and reset inputs cause a state change, and when they don't.

4. NAND-gate Latch The concept of a "latch" circuit is important to creating memory devices. The function of such a circuit is to "latch" the value created by the input signal to the device and hold that value until some other signal changes it.
