为满足未来智能化应用场景的需求，终端电子系统的时效性信息采集和节能性数据处理能力不可或缺。然而，在当前的商业视觉系统中，可见信息由图像传感器收集，转换成数字格式数据，并传送到存储器单元和处理器用于后续处理任务。结果，大部分时间和能量被浪费在数据转换和移动上，这导致大的时间延迟和低的能量效率。在这里，基于2D半导体WSe 2，成功演示了集成可视信息传感-存储-处理能力的逻辑存储晶体管。此外，基于3 × 3的半导体器件，提出了一种人工可视信息感知-存储-处理系统来完成图像识别任务，避免了数据转换和移动带来的时间延迟和能量消耗。另一方面，逻辑存储晶体管还可以同时执行数字逻辑处理（逻辑）和逻辑结果存储（存储），如AND逻辑功能。这种逻辑存储晶体管可以提供一种紧凑的方法来开发下一代高效的视觉系统。展示了一种集成可见信息感测-存储-处理的逻辑存储晶体管。有意义的是，逻辑存储晶体管可以同时执行逻辑处理和逻辑结果存储。逻辑存储晶体管还集成了可见信息传感存储处理功能。此外，还提出了一种人工视觉系统来执行图像区分任务，其中可以避免数据转换和移动。
To meet the demands of future intelligent application scenarios, the time‐efficient information acquisition and energy‐efficient data processing capabilities of terminal electronic systems are indispensable. However, in current commercial visual systems, the visible information is collected by image sensors, converted into digital format data, and transferred to memory units and processors for subsequent processing tasks. As a result, most of the time and energy are wasted in the data conversion and movement, which leads to large time latency and low energy efficiency. Here, based on 2D semiconductor WSe2, a logic‐memory transistor that integrates visible information sensing‐memory‐processing capabilities is successfully demonstrated. Furthermore, based on 3 × 3 fabricated devices, an artificial visible information sensing‐memory‐processing system is proposed to perform image distinction tasks, in which the time latency and energy consumption caused by data conversion and movement can be avoided. On the other hand, the logic‐memory transistor can also execute digital logic processing (logic) and logic results storage (memory) at the same time, such as AND logic function. Such a logic‐memory transistor could provide a compact approach to develop next‐generation efficient visual systems. A logic‐memory transistor with the integration of visible information sensing‐memory‐processing is demonstrated. Meaningfully, the logic‐memory transistor can execute logic prosessing and logic results storage at the same time. The logic‐memory transistor also integrates visible information sensing‐memory‐processing capabilities. Furthermore, an artificical visual system is proposed to perform image distinction tasks, in which data conversion and movement can be avoided.
