Registers
In this lesson, you will learn about
• Registers
• Registers with Parallel load
• Shift registers
• Shift registers with Parallel Load
• Bi-directional Shift Registers
Register
A register is a circuit capable of storing data. In general, an n-bit register consists of n
FFs, together with some other logic that allows simple processing of the stored data.
All FFs are triggered synchronously by the same clock signal. In other words, new data
are latched into all FFs at the same time.
Figure 1 shows a 4-bit register constructed with four D-type FFs. In this figure we have:

Inputs D0 to D3

Clock

Clear/

Outputs Q0 to Q3
The Clock input is common to all the four D FFs. It triggers all FFs on the rising edge of
each clock pulse, and the binary data available at the four D inputs are latched into the
register.
