Abstract

The human memory system plays an indispensable role in oblivion, learning, and memorization. Implementing a memory system within electronic devices contributes an important step toward constructing a neuromorphic system that emulates advanced mental functions of the human brain. Given the complex time-tailoring requirement, integrating a human memory system into one system is a great challenge. Here, one van der Waals heterostructure with flexible time-tailoring ability is demonstrated, which can meet the high requirement of human memory system programming. By stacking volatile and nonvolatile function layers, all basic memory types, including sensory memory, short-term and long-term memory are integrated into the device and the transition between these memory types are flexible. Moreover, decision-making action and in situ result storage are also demonstrated. It is anticipated that the demonstrated time-tailoring system will support the model of a human memory system.
