- Abstract
Combining Boolean logic and nonvolatile memory functions, memristor‐based stateful logic circuits can minimize data movement during the computing process to achieve futuristic in‐memory computing. This may solve the problem of the von Neumann bottleneck in the current computing architecture. Herein, the recent developments in memristor‐based stateful logic computation are discussed from several perspectives, including the device, circuit, operational principles, and applications. Stateful logic gates correspond to in‐memory logic gates, with the inputs and outputs having identical physical entities, such as resistance. The developments in stateful logic primitive gates reported in the past decade are summarized. The influential factors in their actual implementation for stateful logic computation are also discussed. Then, methods for allocating the logic gates into the crossbar array are explained, which are for implementing the complex computing instances in the crossbar array. Finally, several data‐intensive applications achieved using the in‐memory computing method are discussed for the practical application of stateful logic in future computing systems.
