A memristor (/ ˈ m ɛ m r ɪ s t ər /; a portmanteau of memory resistor) is a non-linear two-terminal electrical component relating electric charge and magnetic flux linkage.It was described and named in 1971 by Leon Chua, completing a theoretical quartet of fundamental electrical components which also comprises the resistor, capacitor and inductor.
While the memristor is defined in terms of a two-terminal circuit element, there was an implementation of a three-terminal device called a memistor developed by Bernard Widrow in 1960. Memistors formed basic components of a neural network architecture called ADALINE developed by Widrow. [1] [2] The memistor was also used in MADALINE.
Leon Chua argued that all two-terminal non-volatile memory devices including ReRAM should be considered memristors. [20] Stan Williams of HP Labs also argued that ReRAM was a memristor. [21] However, others challenged this terminology and the applicability of memristor theory to any physically realizable device is open to question.
Military computers will typically also be constructed of more robust materials with more internal structure, more cooling fans, a more robust power supply, and so forth. Intended Environment – An office or consumer computer is intended for use in a very controlled shirt-sleeve environment with moderate temperatures and humidity and minimal dust.
A memory device is built from a grid of such "cells". The simplest method of reading is accomplished by measuring the electrical resistance of the cell. A particular cell is (typically) selected by powering an associated transistor that switches current from a supply line through the cell to ground.
This article lists American military electronic instruments/systems along with brief descriptions. This list specifically identifies electronic devices which are assigned designations according to the Joint Electronics Type Designation System, beginning with the AN/ prefix. They are grouped below by the first designation letter following this ...
They are an electronic device that is used by a sender and when the sender presses on the telegraph key, they interrupt the current creating an audible pulse that is heard at the receiving station. The receiver then decodes the pulses to decode the messages. [2] Since then, military communication has evolved and advanced much further.
This is a list of World War II electronic warfare equipment and code words and tactics derived directly from the use of electronic equipment.. This list includes many examples of radar, radar jammers, and radar detectors, often used by night fighters; also beam-guidance systems and radio beacons.
