What is a phase change memory device?
Phase-change memory (PCM) is a key enabling technology for non-volatile electrical data storage at the nanometer scale. A PCM device consists of a small active volume of phase-change material sandwiched between two electrodes. The stored data can be retrieved by measuring the electrical resistance of the PCM device.
Is phase change memory a memristor?
Abstract: Phase-change memory (PCM) is one of the most promising non-volatile memory technologies and is finding applications in areas such as storage-class memory and emerging non-von Neumann computing systems.
Is used in phase change memory PCM?
Phase change memory uses a special alloys, including Germanium Antimony Tellurium (GST), which have innovative characteristics that enable the non-volatile storage. The alloy can be altered with heat to have two different states or “phases” (crystalline and amorphous) which is how data is stored.
Who invented phase change memory?
Stanford Robert Ovshinsky
Among these new NVM technologies, often called “emerging memories,” the most mature is Phase-Change Memory (PCM). The fundamental mechanism for Phase-Change Memory was invented in the 1960s by Stanford Robert Ovshinsky.
What is a RAM PCM?
Phase-change memory (PCM) is a form of computer random-access memory (RAM) that stores data by altering the state of the matter from which the device is fabricated.
What is the meaning of phase change?
A change in a feature of a physical system that results in a discrete transition of that system to another state. For example, the melting of ice is a phase transition of water from a solid phase to a liquid phase.
How does FRAM work?
The FRAM memory cell operates by applying a switched voltage to sense and restore the data state. The ferroelectric film PZT is about 70nm thick. If the device is placed in a 50 kV field at 1 cm, it is not possible to produce more than 1V across the ferroelectric film.
Is Intel Optane phase change memory?
Intel’s Optane/3D XPoint is a type of phase change memory (PCM). A joint report from Objective Analysis and Coughlin Associates projects the market for persistent memory will exceed $36 billion by 2030, with PCM and magnetoresistive RAM (MRAM) leading the way.
How much is a PCM for a Ram 1500?
Dodge Ram 1500 Powertrain Control Module Replacement Cost Estimate. Labor costs are estimated between $39 and $49 while parts are priced between $887 and $984.
