Abstract: A magnetoresistive random access memory (MRAM) device includes a first array region and a second array region on a substrate, a first magnetic tunneling junction (MTJ) on the first array region, a first top electrode on the first MTJ, a second MTJ on the second array region, and a second top electrode on the second MTJ. Preferably, the first top electrode and the second top electrode include different nitrogen to titanium (N/Ti) ratios.

Abstract: A magnetoresistive random access memory (MRAM) structure, including a substrate and multiple MRAM cells on the substrate, wherein the MRAM cells are arranged in a memory region adjacent to a logic region. An ultra low-k (ULK) layer covers the MRAM cells, wherein the surface portion of ultra low-k layer is doped with fluorine, and dents are formed on the surface of ultra low-k layer at the boundaries between the memory region and the logic region.

Abstract: A computer interface card including a circuit board, a first connector, a second connector, several first conductors, a second conductor, a third conductor, a cover and a base is provided. The first connector is disposed on one side of the circuit board to be electrically connecting to a cable. The second connector, which is disposed on the opposite side of the circuit board, is electrically connected to the first connector and a third connector of a computer. The signal transmitting interface between the second connector and the third connector includes a PCMCIA, a Card Bus or an Express Card Bus interface. The cover and the bottom cover are buckled together to retain the circuit board. The cover and the base have a metal cover and a metal base respectively, wherein the metal cover is electrically connected to the first conductors and the metal base.
