Data Registers
Data registers are used in microcomputers to hold data temporarily. Normally this data can be accessed faster than if it were to be fetched from the memory. The figure below shows a 4-bit data register that utilizes a negative edge-triggered D flip-flops to transfer data from four data lines to the outputs of four AND…

Flip-Flops in Digital Circuits
Since digital data is usually stored in the form bits, digital memory devices such as the computer random access memory (RAM) requires a way for storing and switching between the two binary states. A flip-flop is a sequential logic device that can perform this operation. The flip-flop is called a bistable device, because it has…
