Multioperation Mode Ferroelectric Channel Devices for Memory and Computation

The traditional von Neumann architecture separates memory from the central processing unit (CPU), resulting in aggravated data transfer bottlenecks between the CPU and memory during a data volume surge. Emerging technologies, such as in-memory computing (IMC), provide a new way to overcome the limitations due to the separation of memory and computation. However, existing IMC efforts are generally limited to a single (gate-control or drain-control) mode of operation to achieve functionality. Herein, a 2D ferroelectric channel device that enables the feasibility of multioperation modes is proposed. In addition, rich functionalities, such as logic, nonvolatile memory, and neuromimetic plasticity modulation, by switching the operating modes are realized. A device that facilitates multimodal operations and a promising technical solution for further development of burgeoning computing architecture is provided.
