Abstract: A memory device may include a bottom electrode, first and second switching elements over the bottom electrode, and first and second top electrodes over the first and second switching elements respectively. The first and second top electrodes may include first and second contact surfaces in contact with the first and second switching elements respectively. The first and second switching elements may each have a resistance configured to switch between resistance values in response to changes in voltages applied between the top electrodes and the bottom electrode. The bottom electrode may include at least one conductive layer having third and fourth contact surfaces in contact with the first and second switching elements respectively. An area of the first contact surface may be greater than an area of the third contact surface, and an area of the second contact surface may be greater than an area of the fourth contact surface.

Abstract: A memory device may include a substrate having conductivity regions and a channel region. A first voltage line may be arranged over the channel region. A second voltage line, and third and fourth voltage lines may be electrically coupled to a first conductivity region and a second conductivity region respectively. Resistive units may be arranged between the third and fourth voltage lines and the second conductivity region. In use, changes in voltages applied between the second and third voltage lines, and between the second and fourth voltage lines may cause resistances of first and second resistive units to switch between lower and higher resistance values. The lower resistance value of the first resistive unit may be different from the lower resistance value of the second resistive unit and/or the higher resistance value of the first resistive unit may be different from the higher resistance value of the second resistive unit.

Abstract: A sensor device includes a substrate, first and second source regions, first and second drain regions, first and second channel regions, and first and second gate structures disposed over the first and second channel regions respectively. The source regions and drain regions are at least partially disposed within the substrate. The second gate structure includes first and second gate elements, and a resistance region configured to provide a resistance to a second current flow through the second channel region. In use, the first gate structure may receive a solution, and a change in pH in the solution changes a first current flow through the first channel region. In turn, the second current flow through the second channel region changes to compensate for the change in the first current flow to maintain a constant current flow through the sensor device.

Abstract: A non-volatile memory device includes a substrate, a gate stack structure, an erase gate structure, and a ferroelectric layer. The gate stack structure is disposed on the substrate. The erase gate structure is disposed on the substrate and disposed at a first side of the gate stack structure. The ferroelectric layer is disposed on a sidewall of the gate stack structure, and the ferroelectric layer is disposed between the gate stack structure and the erase gate structure. The ferroelectric layer disposed between the gate stack structure and the erase gate structure may be used to forma negative capacitance effect for amplifying the voltage applied to the erase gate structure. The purpose of reducing power consumption may be achieved accordingly.
