Abstract

A non-volatile latch circuitry, comprising a Re RAM cell configured to store a final value of the non-volatile latch circuitry; a data selection circuitry configured to connect or disconnect a data input to a plus voltage node and a minus voltage node of the Re Ram cell depending on a clock input voltage level; a pull down transistor configured to set a first voltage level at the minus voltage node to a logically low voltage level if the data input is not connected to the plus and minus voltage nodes of the Re RAM cell; a bias circuitry configured to provide a fix bias current to set a second voltage level at the plus voltage node to a varying voltage level depending on the resistor value of the Re RAM cell if the data input is not connected to the plus voltage node; and a threshold adjusted circuitry arranged to convert an analog value of the second voltage level into a digital value and configured to generate an output signal and / or an inverted output signal.

Random-access memory

Random-access memory (RAM; ræm) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement.

Voltage

Voltage, also known as electric pressure, electric tension, or (electric) potential difference, is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a test charge between the two points. In the International System of Units (SI), the derived unit for voltage is named volt. The voltage between points can be caused by the build-up of electric charge (e.g., a capacitor), and from an electromotive force (e.g.

Voltage multiplier

A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage, typically using a network of capacitors and diodes. Voltage multipliers can be used to generate a few volts for electronic appliances, to millions of volts for purposes such as high-energy physics experiments and lightning safety testing. The most common type of voltage multiplier is the half-wave series multiplier, also called the Villard cascade (but actually invented by Heinrich Greinacher).
