Latching device and method

Abstract

According to one embodiment of the present disclosure, an apparatus is provided. The apparatus comprises a data input to receive a data signal. The apparatus further comprises a latching circuitry. The latching circuitry comprises a first Correlated Electron Switch(CES) element and a second CES element. The latching circuitry further comprises a control circuit coupled to the first CES element andthe second CES element. The control circuit is configured to program impedance states of the first CES element and the second CES element based on the data signal.

Description

technical field [0001] The present disclosure relates to data storage circuits, and more particularly to latching circuits including associated electronic switching (CES) elements. Background technique [0002] A flip-flop or latch is a circuit that has two stable states and can be used to store state information. Such circuits are commonly used as data storage elements. A single latch stores one bit of data as long as the latch circuit is powered. Also, whenever the enable signal is asserted, the output of the latch circuit changes based on the input. Typical latch circuits are volatile, that is, data stored in the latch circuit is lost when power to the latch circuit is removed. Conventional techniques for enabling a latch circuit to hold data include coupling the latch circuit with its own independent power supply to the holding latch. In this technique, the data stored in the latch circuit is copied to the holding latch when the power to the latch circuit is cut off....

Problems solved by technology

However, this approach requires redundant circuitry, which requires additional space in the integrated circuit to be otherwise reserved

Also, an additional power supply is required, increasing the overall power consumption of the latch circuit
