Fig. 1: The hardware implementation schematic of neural reuse, alongside the illustrative diagram of the reconfiguration and refresh strategies.

a Schematic of neural reuse, where shared original neural circuits are specialized across multiple tasks through redeployment (blue arrow) and restoration (red arrow) processes. b Schematic hardware implementation of neural reuse, encompassing the refresh and restore process, along with the cyclic configuration between source model and task model. c Schematic of the reconfiguration strategy and the refresh strategy. It encompasses characteristics of switching between volatility and non-volatility, as well as the allocation of them across diverse tasks. d Schematic of the refreshable memristor proposed in this work. The left and right sides of the diagram represent the energy barriers that need to be crossed for ferroelectric polarization reversal and ion migration, respectively. The dynamic allocation of order-disorder phases in CuInP₂S₆ allows for the circular configuration of two distinct memristive mechanisms within a single material.
