Abstract: Disclosed are a high-throughput preparation device for metal fiber based on multi powder and a method for preparing a metal fiber using the device. The high-throughput preparation device includes a metal powder conveying system, a metal powder mixing system, a metal powder melting system and a metal fiber forming system which are connected in sequence, where the metal powder melting system includes an induction powder melting device and a laser powder melting device which are independently disposed. The method for preparing a metal fiber using the high-throughput preparation device includes four steps: powder conveying, powder mixing, melting and forming.

Abstract: The present invention discloses a multi-bit-per-cell three-dimensional resistive random-access memory (3D-RRAMMB). It comprises a plurality of RRAM cells stacked above a semiconductor substrate. Each RRAM cell comprises a RRAM layer, which is switched from a high-resistance state to a low-resistance state during programming. By adjusting the programming current, the programmed RRAMs have different resistances.
