- It can be constructed from a pair of cross-coupled NOR logic gates. The stored bit is present on the output marked Q. While the S and R inputs are both low, feedback maintains the Q and Q outputs in a constant state, with Q the complement of Q.
electronics-course.com/sr-nor-latch Latches in Digital Logic - GeeksforGeeks
Latches are digital circuits that store a single bit of information and hold its value until it is updated by new input signals. They are used in digital systems as temporary storage elements to store binary information. Latches can be implemented using various digital logic gates, such as AND, OR, NOT, NAND, and … See more
In digital electronics different types of latches are: 1. SR Latches 2. Gated SR Latches 3. D Latches 4. Gated D Latches 5. JK Latches 6. T … See more
S-R latches i.e., Set-Reset latches are the simplest form of latches and are implemented using two inputs: S (Set) and R (Reset). The S input sets the output to 1, while the R input resets the output to 0. When both S and R inputs are at 1, the latch is said to be in … See more
A Gated SR latch is a SR latch with enable input which works when enable is 1 and retain the previous state when enable is 0. See more

NOR gate - Wikipedia
The NOR gate is a digital logic gate that implements logical NOR - it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator. It can also in some senses be seen as the inverse of an AND gate. NOR is a functionally complete operation—NOR gates can be combined to generate any other logical function. It shares this pr…
