    摘要: Provided is a stacked magnetic random access memory (MRAM) in which memory cell arrays having various characteristics or functions are included in memory cell layers. The stacked MRAM device includes a semiconductor substrate and at least one memory cell layers. The semiconductor substrate includes a first memory cell array. Each of the memory cell layers includes a memory cell array having a different function from the first memory cell array and is stacked on the first memory cell array. As a result, the stacked MRAM device has high density, high performance, and high reliability.

    摘要: A memory device includes a memory cell array including a plurality of memory cells, each including a bidirectional variable resistance element and an input/output circuit configured to determine a polarity for a read voltage to be applied to a selected memory cell among the plurality of memory cells and to apply the read voltage with the determined polarity to the selected memory cell. The input/output circuit may include a polarity determination circuit configured to determine the polarity responsive to a determination mode signal and a driver circuit configured to apply the read voltage with the determined polarity to the selected memory cell.

    摘要: A method of programming a one-time programmable device is provided. A switching device disposed in a substrate is turned on and a program current is applied to a fuse electrically connected to the switching device, thereby cutting the fuse. The fuse includes a first electrode electrically connected to the switching device, a second electrode spaced apart from the first electrode, and a chalcogenide pattern disposed between the first and second electrodes. Related one-time programmable devices, phase change memory devices and electronic systems are also disclosed.
