Abstract
A CMOS shift register cell comprising four transistors and two capacitance elements. Data is temporarily stored in the cell by precharging one capacitance through one of the transistors and then discharging it or not through another of the transistors depending on the input signal level. The second capacitance may be precharged through the third transistor and then discharged or not through the fourth transistor, depending upon the value of the temporarily stored charge.
