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 display system includes a display device and an HDMI dongle electrically connected to the display device. The display device includes a first transmission interface, a first control module, and a power supply module. The HDMI dongle includes a second transmission interface and a second control module. The first and the second transmission interfaces include transmission pins corresponding to each other. The first control module detects voltage of one pin to obtain matching state between the display device and the HDMI dongle and outputs an enabling signal. When the HDMI dongle matches the display device, the enabling signal controls the power supply module to transmit the power supply signal to the second control module through the first and the second transmission interfaces for charging the second control module. When the HDMI dongle does not match the display device, the power supply module is not transmitted to the second control module.

Abstract: A mounting platform assembly for a stand device includes a connecting platform having two parallel engaging blocks projecting from a bottom surface thereof, each having a positioning hole and forming a slope on an outward face thereof; and a fixing base having two engaging ribs projecting from a top surface thereof, each forming a sliding groove on the top surface of the fixing base corresponding to the slope of each engaging block, and the fixing base having a positioning means including an engaging button and a push rod. When a conical portion of the push rod abuts against a bottom end of the engaging button, the other end of the engaging button projects from the top surface of the fixing base to engage with the positioning hole of the engaging block, thereby achieving the positioning and fixing of the connecting platform.
