SR Latch Using NOR Gate | How Do Computers Remember?

This video shows how to build an SR Latch using NOR Gate. A Latch is a digital circuit that has two stable states viz. high and low outputs. The feedback path allows the device to retain the information. Hence, Latches are memory devices that can store one-bit data. SR Latch or Set/Reset Latch has two inputs, S and R, and two outputs Q and Q'. When the input to the Set line goes high, output Q goes high (and Q' goes low). The output at Q will continue to remain high even when input at Set goes low again. When the input to the Reset line goes high, output Q goes low (and Q' goes high). This means resetting the memory of the Latch. Tinkercad Software is used to make the schematic.
