Mitrofanov, Kotaro Makino, Junji Tominaga, and John Robertson, Applied Physics Letters (2019). Integrated phase-change photonic memory devices offer a novel route to non-volatile storage and computing that can be carried out entirely in the optical domain, obviating the necessity for time and energy consuming opto-electrical conversions. Phase change memory is widely considered as the most promising candidate as storage class memory (SCM), bridging the performance gaps between dynamic random access memory and flash. Phase-change materials (PCMs) show great promise to break this bottleneck by enabling nonvolatile memory devices that can optimize the complex memory hierarchy, and neuro-inspired computing devices that can unify computing with storage in memory cells. We present a simple model that is useful in describing such emerging memory technologies for use in com-puter architecture studies. IEEE Xplore, delivering full text access to the world's highest quality technical literature in engineering and technology. PCM devices are susceptible to noise, resistance-drift, non-symmetric and non-linear conductance change in response to an electrical stimulus, and reliability concerns. Phase-change memory (PCM) was proposed by Stanford Ovshinsky in 1968.

However, it comprises memory cells that have limited lifetime and higher access latency than DRAM. IEEE Electron Device Letters 2019 , 40 (10) , 1595-1598. We studied the atomic layer deposition (ALD) and the tellurization of Ge–Sb films to prepare conformal crystalline Ge–Sb–Te (GST) films and to achieve void-free gap filling for emerging phase-change memory applications. ALD Ge–Sb film was prepared by alternating exposures to GeCl2-dioxane and Sb(SiEt3)3 precursors Interfacial phase‐change memory (iPCM) was invented to improve the problem in 2008. First published on 7th November 2018. Phase change memory (PCM) elements include phase change materials, such as chalcogenide alloys, that are capable of stably transitioning between amorphous and crystalline phases. Herein, we propose a low-cost and facile method to develop a flexible electro-driven phase change composite with unidirectional shape memory effects and motion detection properties. Phase change memory is based on a technique known as the memresitor that was initially developed by Hewlett Packard. However, high required operation current remains the major limitation for the SCM application, even after using defect engineering materials, for example, Ti-doped Sb2Te3.
