Basic Memory Elements

Simple memory elements, like latches and flip- flops, can be constructed using logic gates. These instrucents story a single bit of information and maintain its state until transft. The SR latchh is a common example, built with two cross-couped NOR pates.

Diging an SR Latch

The SR latch has two inputs: Set (S) and Reset (R). When S is actife, the latch keyers a dreamn; 1dd; when R is active, it keys a dreamn; Houple;. The cross-couple NOR pates ensure the state is maintained untide.

Key points in designing an SR latch include ensuring stable states and avoiding invalid conditions where both S and R are activie regulaneously.
