Continuous memristors have been widely used in various chaotic circuits as well as neuromorphic circuits, but there is a relative lack of research on discrete memristors. In this paper, a new three-dimensional memristor hyperchaotic map is proposed by coupling the discrete memristor with a simple two-dimensional map. The fixed points of the map are analysed and the dynamical behaviour of the typical parameters of the map and the initial boosting is investigated using numerical simulations. For practical engineering needs, offset boosting and amplitude control of the map are performed without destroying the basic structure of the map. Finally, a simple image encryption algorithm is designed using this three-dimensional memristor hyperchaotic mapping, which has been verified to be well randomized.
