Self-Powered Memory Systems

Abstract: Artificial intelligence memory is expected to acquire, calculate, and analyze a large amount of logical information and data in time to dynamically respond to artificial neural networks. It is the most promising candidate for realizing a new hardware artificial intelligence architecture that mimics biological neural networks. However, the research on artificial intelligence memory is still in the initial stage, and there are some unresolved bottlenecks for the preparation of artificial intelligence memory devi… Show more

“…Therefore, since an external voltage is applied between the top electrode Ag and the bottom electrode A1, the movement of carriers will be limited near the interface, and the Schottky barrier region is equivalent to a tunnel gap. 56 In addition, the decrease of the potential barrier can give rise to a significant increase of the field-effect mobility in the IGZO semiconductor according to the percolation conduction model. 57 In other words, a chargelimited region will be formed at the three interfaces of Ag/ IGZO, IGZO/TiO 2 , and TiO 2 /Al, which further leads to the formation of an internal electric field in the charge limited area, and its direction is opposite to the direction of the external electric field.…”

“…Because the electron mobility in the IGZO layer has an exponential relationship with the height of the Schottky barrier, , the reduction of the potential barrier can lead to a significant increase in electron mobility. Therefore, since an external voltage is applied between the top electrode Ag and the bottom electrode A1, the movement of carriers will be limited near the interface, and the Schottky barrier region is equivalent to a tunnel gap . In addition, the decrease of the potential barrier can give rise to a significant increase of the field-effect mobility in the IGZO semiconductor according to the percolation conduction model .…”

“…The V o -and H 2 O-related redox reaction is easily triggered. [196][197][198][199][200][201] The V o possibly is compensated or weaken by the electron contributed by the redox reaction or light stimulation. In this case, the unique physical effects such as the NDR and are possibly emerging in the anion-based memristor.…”

“…The increase and decrease of conductance can simulate the potentiation and depression of synapses . The ReRAM has the advantages of nonvolatile, fast read/write speeds, ultrasmall size, and low power consumption . The resistance states can be changed by regulating the flux of charge carriers (ie, ions and electron carriers) flowing through the device. , Many physical models have been reported to explain the memristive behaviors of ReRAM devices.…”
