Last time, we saw how latches can be used as memory in a circuit.. Latches introduce new problems:. We need to know when to enable a latch.. We also need to quickly disable a latch..

A . latch. is a temporary storage device that has two stable states (bistable). It is a basic form of memory. . The S-R (Set-Reset) latch is the most basic type. It can be constructed from NOR gates or NAND gates. With NOR gates, the latch responds to active-HIGH inputs; with NAND gates, it responds to active-LOW inputs.. © 2014 Project Lead The Way, Inc..
