Abstract: A variable resistive memory device includes a memory cell, a first circuit, and a second circuit. The memory cell is connected between a word line and a bit line. The first circuit provides the bit line with a first pulse voltage based on at least one enable signal. The second circuit provides the word line with a second pulse voltage based on the enable signal. The first circuit generates the first pulse voltage increased in steps from an initial voltage level to a target voltage level.

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 bit line, a word line crossing the bit line, and a memory cell coupled to and disposed between the bit line and the word line. In a read operation, when the word line, which is in a precharged state, is floated, the bit line is driven to increase a voltage level of the bit line, and stopped when the memory cell is turned on.
