Abstract: A sense amplifier circuit includes a sense amplifier, a switch and a temperature compensation circuit. The temperature compensation circuit provides a control signal having a positive temperature coefficient, based on which the switch provides reference impedance for temperature compensation. The sense amplifier includes a first input end coupled to a target bit and a second input end coupled to the switch. The sense amplifier outputs a sense amplifier signal based on the reference impedance and the impedance of the target bit.

Abstract: A bottom-pinned spin-orbit torque magnetic random access memory (SOT-MRAM) is provided in the present invention, including a substrate, a bottom electrode layer on the substrate, a magnetic tunnel junction (MTJ) on the bottom electrode layer, a spin-orbit torque (SOT) layer on the MTJ, a capping layer on the SOT layer, and an injection layer on the capping layer, wherein the injection layer is divided into individual first part and second part, and the first part and the second part are connected respectively with two ends of the capping layer.

Abstract: A paint-supplying device (14) for supplying paint to a paint chamber (11) is provided. The paint-supplying device includes an accommodating cavity (143) and a plurality of paint barrels (145). The accommodating cavity is integrally defined with the paint chamber. The accommodating cavity communicates with the paint chamber. The plurality of paint barrels is accommodated in the accommodating cavity and configured for supplying paint to the paint chamber. A paint-spraying system (10) using the present paint-supplying device is further provided.
