Abstract: A memory device comprises a source region, a drain region, a channel region, a gate dielectric layer, an MTJ stack, and a metal gate. The source region and the drain region are over a substrate. The channel region is between the source region and the drain region. The gate dielectric layer is over the channel region. The MTJ stack is over the gate dielectric layer. The MTJ stack comprises a first ferromagnetic layer, a second ferromagnetic layer with a switchable magnetization, and a tunnel barrier layer between the first and second ferromagnetic layers. The metal gate is over the MTJ stack.

Abstract: An integrated circuit layout structure and method thereof establishes cell rows with different cell heights for accommodating cells with corresponding heights, such that an area of an integrated circuit can be fully utilized. Therefore, it reduces an area wasted by an unnecessary uniform cell height, so as to improve integration of the integrated circuit.

Abstract: An impact sensor for installation in a moving machine to detect an impact includes first and second electrically conductive strip and an insulative layer sandwiched therebetween. The first electrically conductive strip has at least one electrically conductive member facing but insulatively separated by the insulative layer from at least one electrically conductive member of the second electrically conductive strip. The insulative layer has a plurality of through holes, through at least one of which the electrically conductive member of the first electrically conductive strip and the electrically conductive member of the second electrically conductive strip are electrically contactable with each other when the second electrically conductive strip deforms under impact.

Abstract: A floor-cleaning device primarily comprises a pair of driving units provided at two opposite sides of a main body thereof wherein the driving units are electrically connected to a control unit and a power-supply unit which are both deposited in the main body so that the main body is capable of moving freely on a substantial surface. Particularly, a moving-along-edge sensing unit is provided at the left or right side of the main body to conduct a movement of the main body along the edge of the surrounding objects. The sensing unit is composed of non-contact sensing components so as to permit the main body to move along the edge of the surrounding objects with a predetermined distance in a continuous slightly oscillatory S-shaped route. In virtue of the sensing unit, the main body can automatically approach and connect to a charger for automatic charge.
