Abstract: A magnetic random access memory (MRAM) structure is provided. The MRAM structure includes a first write electrode, a first magnetic tunnel junction (MTJ) stack, a voltage control electrode, a second MTJ stack, and a second write electrode. The first MTJ stack includes a first free layer disposed on the first write electrode, a first tunnel barrier layer disposed on the first free layer, and a first fixed layer disposed on the first tunnel barrier layer. The voltage control electrode is disposed on the first MTJ stack. The second MTJ stack includes a second fixed layer disposed on the voltage control electrode, a second tunnel barrier layer disposed on the second fixed layer, and a second free layer disposed on the second tunnel barrier layer. The second write electrode is disposed on the second MTJ stack.

Abstract: A structure of an electrochemical unit includes a substrate, a first metal layer disposed on the substrate, and an array of electrochemical cells disposed on the first metal layer. The array of the electrochemical cells includes a plurality of electrochemical cells. Each of the electrochemical cells includes the first metal layer disposed on the substrate, a first electrode disposed on the first metal layer, a polymer layer disposed on the substrate and adjacent to the first metal layer and the first electrode. A second metal layer is disposed on the polymer layer, and a second electrode is disposed on the second metal layer. A pore is constituted between the polymer layers of every the two electrochemical cells. A cavity located above the first electrode is defined between every the two electrochemical cells, wherein the cavity is communicated with the pore.
