  • Publication number: 20210110871
    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.
