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.
In one of the technical reports [3] the memistor was described as follows: . Like the transistor, the memistor is a 3-terminal element. The conductance between two of the terminals is controlled by the time integral of the current in the third, rather than its instantaneous value as in the transistor.
On the other hand, a cross-point architecture is more compact and may enable vertically stacking memory layers, ideal suited for mass-storage devices. However, in the absence of any transistors, isolation must be provided by a "selector" device, such as a diode, in series with the memory element or by the memory element itself. Such isolation ...
Hardware architecture is the representation of an engineered (or to be engineered) electronic or electromechanical hardware system, and the process and discipline for effectively implementing the design(s) for such a system. It is generally part of a larger integrated system encompassing information, software, and device prototyping. [2]
Event 600 BCE: Ancient Greek philosopher Thales of Miletus described static electricity by rubbing fur on substances such as amber. 1600: English scientist William Gilbert coined the word electricus after careful experiments. He also explained the magnetism of Earth. 1660: German scientist Otto von Guericke invented a device that creates static ...
Familiarity with unified modeling language (UML) is needed to construct a system sequence diagram. These models show the logic behind the actors (people who affect the system) and the system in performing the task. Reading a sequence diagram begins at the top with the actor(s) or the system(s) (which is located at the top of the page).
Overview of the forms and functions of memory. Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed.It is the retention of information over time for the purpose of influencing future action. [1]
A direct-access storage device (DASD) (pronounced / ˈ d æ z d iː /) is a secondary storage device in which "each physical record has a discrete location and a unique address". The term was coined by IBM to describe devices that allowed random access to data, the main examples being drum memory and hard disk drives. [1]
