P8P parallel phase change memory (PCM) is nonvolatile memory that stores informa-tion through a reversible structural phase ch ange in a chalcogenide material. Resistive random-access memory (ReRAM or RRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a dielectric solid-state material, often referred to as a memristor.This technology bears some similarities to conductive-bridging RAM (CBRAM), and phase-change memory (PCM).. CBRAM involves one electrode providing ions that … In particular, multi-level cell (MLC) PCM that stores multiple bits in a single cell, offers high density with low per-byte fabrication cost. PCM possesses the ability to change their state with a certain temperature range. Phase change memory uses a semiconductor alloy that can be changed rapidly between an ordered, crystalline phase having lower electrical resistance to a disordered, amorphous phase with much higher electrical resistance.

Abstract: We discuss novel multi-level write algorithms for phase change memory which produce highly optimized resistance distributions in a minimum number of program cycles. Ge-Sb-Te materials are used in optical DVDs and non-volatile electronic memories (phase-change random-access memory). Phase-change nonvolatile semiconductor memory technology is based on an electrically initiated, reversible rapid amorphous-to-crystalline phase-change process in multicomponent chalcogenide alloy materials similar to those used in rewriteable optical disks. Phase Change Memory (PCM) ‏. Voltage polarity effects in Ge2Sb2Te5-based phase change memory devices. 1 (A to D). Phase change based memory devices and methods for operating such devices described herein overcome the set or reset failure mode and result in improved endurance, reliability and data storage performance. However, it has the inevitable endurance problem of the storage cells. PCM devices are resistive memory devices that can be programmed to achieve a desired conductance value by altering the amorphous (melting) and crystalline (hardening) phase configuration within the device. Random Access Memory Static RAM SDRAM Dynamic RAM DRAM Content-addressable memory Cache Controller. 1A as the functional element to demonstrate scalar multiplication of two numbers. We used the photonic memory device with phase-change materials shown in Fig. Phase change materials (PCM) take advantage of latent heat that can be stored or released from a material over a narrow temperature range. The memory cell is built by layering a storage element and a selector. And. This will apply to all substances, but we are all most familiar with water. Phase Change Memory offers the promise of fast RAM speeds, but can be used to store data with low power requirements.
