From the explanation, it is clear that the dynamic shift registers store the information in the form of charge on the gate-to-substrate parasitic capacitance of the electronic (especially MOS) devices.

Dynamic Logic Dynamic logic circuits offer several significant advantages over static logic circuits. Static current through the circuit is 0. Dynamic CMOS In static circuits at every point in time (except when switching) the output is connected to either GND or V DD via a low resistance path. The operation of MOS dynamic circuits are explained and charge sharing and charge leakage problems associated with MOS dynamic circuits are introduced. Results and Discussion The performance analysis of static and dynamic CMOS circuits is carried out.
2 Introduction • Combination logic circuit – Performing Boolean operations between input and output – Static and dynamic characteristics • MOS depletion-load gates – Emphasize the load concept – NAND, NOR • CMOS logic circuit • CMOS transmission gates Complementary metal–oxide–semiconductor (CMOS), also known as complementary-symmetry metal–oxide–semiconductor (COS-MOS), is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. The clock skew problem of MOS dynamic circuits is also discussed. The operation of domino-complementary metal–oxide–semiconductor (CMOS) and (NO Race) NORA-CMOS dynamic circuits is explained. The operation of all dynamic logic gates depends on temporary storage of charge in parasitic node capacitances, instead of relying on steady-state circuit behavior. This is in contrast to the dynamic circuit class, which relies on temporary storage of signal values on the capacitance of high impedance circuit nodes.
