Abstract: An electronic device includes a semiconductor memory. The semiconductor memory includes word lines, bit lines intersecting the word lines, and memory cells coupled to and disposed between the word lines and the bit lines, each of the memory cells including a variable resistance layer in an amorphous state regardless of a value of data stored in the memory cells. In a reset operation, a memory cell is programmed to a high-resistance amorphous state by applying, to the memory cell, a sub-threshold voltage that is lower than a lowest threshold voltage among threshold voltages of the memory cells.

Abstract: An electronic device includes a semiconductor memory. The semiconductor memory includes a word line, a bit line, and a memory cell coupled to and disposed between the word line and the bit line, the memory cell including a variable resistance layer that remains in an amorphous state regardless of a value of data stored in the memory cell. In a reset operation, the memory cell is programmed to a high-resistance amorphous state by applying, to the memory cell, a sub-threshold voltage that is greater than 0.7 time of a threshold voltage of the memory cell and is smaller than 0.95 time of the threshold voltage.

Abstract: A chalcogenide material may include germanium (Ge), arsenic (As), selenium (Se) and from 0.5 to 10 at % of at least one group 13 element. A variable resistance memory device may include a first electrode, a second electrode, and a chalcogenide film interposed between the first electrode and the second electrode and including from 0.5 to 10 at % of at least one group 13 element. In addition, an electronic device may include a semiconductor memory. The semiconductor memory may include a column line, a row line intersecting the column line, and a memory cell positioned between the column line and the row line, wherein the memory cell comprises a chalcogenide film including germanium (Ge), arsenic (As), selenium (Se), and from 0.5 to 10 at % of at least one group 13 element.
