Abstract: This specification describes a sense amplifier/bit driver circuit for a monolithic memory storage cell with a double ended output. The sense amplifier consists of two shunt feedback amplifiers connected differentially across the double ended output of the storage cell. There is a resistive connection between the outputs of the two shunt feedback amplifiers to make each input of the two shunt feedback amplifiers relatively insensitive to large changes at the other input. The bit driver for the circuit contains two current switch circuits for controlling the potential at each end of the double ended output of the storage cell. These current switch circuits are crosscoupled by a transistor which eliminates the need for inverting one of the control pulses to the bit driver.

Abstract: This specification discloses an A.C. stable or stored charge storage cell for use in monolithic memories. The cell includes a capacitor that couples a drive line to a sense line. The capacitance of this capacitor is voltage dependent so that when charged it provides a high capacitance to couple signals on the drive line to the sense line and when discharged it provides a low capacitance to prevent the coupling of signals from the drive line to the sense line.
