The progress of Moore’s law has been fueling a growing-demand for computing. However, there is a gap between the amount of data generated and computing efficiency. The two main reasons are the saturation of processing speed, and the bottleneck which appears between the storage and computing unit. Because the processing unit and storage unit of a von Neumann computer are located separately, there is a time delay for data to move from one unit to another, which is called ‘data bus’. We can eliminate the ‘data bus’ itself by designing a new hardware which makes possible in-memory operations. In the case of redox RSMs, the redox reaction rate and ion migration speed decides the switching speed. The Electro chemical mechanism refers to using an electrochemically active metal for the top electrode. The ReRAM works through the creation of filaments made of ions or vacancies, therefore the halide perovskite is a promising material for resistive switching. Also, they allow facile fabrications and are easy to tune the bandgap through controlling the types and the ratio of Halogen elements. Herein copper based HPs, which are eco-friendly and relatively environmentally stable, are suggested as artificial synapses. Typical synaptic behaviors such as potentiation and depression, SVDP, SWDP are demonstrated that. |
