Abstract: A magnetoresistive random access memory (MRAM) includes a first transistor and a second transistor on a substrate, a source line coupled to a first source/drain region of the first transistor, and a first metal interconnection coupled to a second source/drain region of the first transistor. Preferably, the first metal interconnection is extended to overlap the first transistor and the second transistor and the first metal interconnection further includes a first end coupled to the second source/drain region of the first transistor and a second end coupled to a magnetic tunneling junction (MTJ).

Abstract: An arm muscle exerciser includes a main stand, a base plate, two handles and several weight discs; the upper part of the main stand is a smaller diameter section with a smaller outer diameter; the base plate is joined to the bottom of the main stand; each end of the two handles has an end pivotally attached to a respective one of a pair of parallel pivot axles on opposite sides of the upper part of the main stand such that they pivot symmetrically in a plane; in the weight disc is an accommodating hole; at one side of the accommodating hole is an opening; the smaller diameter section of the main stand may be inserted into the accommodating hole through the opening, and slide down along the outer diameter of the main stand to fall onto the base plate, so the base plate will support an appropriate number of weight discs.
