In this paper, we show that Phase Change Memory (PCM) can be used to emulate specific functions of a biological synapse similar to Long Term Potentiation (LTP) and Long Term Depression (LTD) plasticity effects. The dependence of synaptic weight on programming pulse width and pulse amplitude is shown experimentally for the PCM devices. Different combinations(More)
In order to simulate the electro-thermal characteristics of our devices and to reproduce the phase change mechanisms of the PCM material during the set and reset operations, we have developped a finite element electro-thermal solver coupled with the Phase Field Method. Retention simulations for full GST layers are first presented. Then set simulations, with(More)
Digital Object Identifier: 10.1109/JPROC.2017.2710217 in state-of-the-art SSDs is the nand Flash memory technology, therefore the figures of merit of a drive are largely dictated by those of the Flash. Their continuous technology scaling to provide larger storage densities is however exposing a struggle for achieving an inherent level of reliability and(More)
