Co-integrated vertical transistor selectors (1T) and resistive memory elements (1R) in a 1T1R configuration offer advantages of scalability, speed and energy efficiency in current mass storage applications, and such 1T1R cells could also be potentially used for in-memory computation architectures. Here we show that a vertical transistor and resistive memory can be integrated onto a single vertical indium arsenide nanowire on silicon. The approach relies on an interface between the III-V semiconductor nanowire and a high-kappa dielectric (hafnium oxide), which provides an oxide layer that can operate either as a vertical transistor selector or a high-performance resistive memory. The resulting 1T1R cells allow Boolean logic operations to be implemented in a single vertical nanowire with a minimal area footprint.A vertical transistor and resistive memory can be integrated on a single vertical III-V semiconductor nanowire on silicon, creating a compact cell capable of Boolean logic operations. 收起
