The emergence of artificial intelligence has revealed the limitations traditional von Neumann computing systems in fulfilling current computational requirements. In-memory (IMC) been generally considered as a promising architecture to break bottleneck, where FeFET is strong candidate for developing IMC hardware, but remains challenging. In this work, we demonstrate complementary metal oxide semiconductor-compatible In2O3 array neuromorphic computing. FeFETs exhibit excellent performance, including an ultrahigh on-off ratio (107), large memory window (>6 V), high endurance (107 cycles), long retention time (>10 years), low cycle-to-cycle variation (1.1%), uniformity, and highly linear symmetrical long-term potentiation (LTP)/long-term depression (LTD).

Highly sensitive sensors are critical for in-sensor computing, an ultrafast and low-power machine vision technology. However, capturing sharp images without motion blur in low-light high-speed situations remains challenging due to weak photoresponse. Here, we present a heterostructure ferroelectric phototransistor leveraging opto-electrical decoupling fast perception computing. The channel is preprogrammed low-resistance state via polarization, while light modulates the drain current through light-induced depolarization. This mechanism enables record-high MoTe2-based photoresponsivity of 3.05×104 A/W by optimizing balance between depolarization screening fields. can perceive pulses as short 200 μs, achieving operating frequency 5 kHz energy consumption 74 fJ.
