6MEMORY AND CLOCK SIGNALS
In the previous chapters we saw how digital logic gates can be combined to produce useful combinational logic circuits where the output is a function of the inputs. In this chapter, we look at sequential logic circuits. These circuits have memory, the ability to store a record of the past. We cover some specific kinds of memory devices: latches and flip-flops. We also learn about clock signals, which are a way to synchronize multiple circuit components.
Sequential Logic Circuits and Memory
Let’s now examine a type of digital circuit known as a sequential logic circuit. A sequential logic circuit’s output depends not ...
