Problems solved by technology

In ultra-light wearable electronic products, medical health monitoring, robots, remote sensing and other systems, data storage devices are an essential part, but ultra-light memory technology is still relatively lacking.
Among many memory devices, resistive memory is considered to be the next-generation memory due to its advantages such as good scalability, high storage density, low power consumption, fast read and write speed, strong resistance to repeated operations, and long data retention time. One of the most powerful candidates, but the resistive memory of the existing technology is generally heavy

Abstract

The invention discloses a super-light resistive random access memory and a preparation method thereof. The super-light resistive random access memory comprises a metal thin-film electrode; a first silk protein film and a second silk protein film cover an upper layer and a lower layer of the metal thin-film electrode respectively; and a silver thin-film electrode covers the first silk protein film. The light silk protein is used as a substrate and is also used as a resistive material, so that the resistive random access memory with the mass per unit area of 4mg/cm<2> can be obtained; and the mass per unit area of the resistive random access memory is smaller than that of the silicon-substrate-based traditional resistive random access memory by over 320 times and is smaller than that of the common A4 paper by over 20 times.
