Abstract
A storage device includes a memory cell including first and second layers and a memory layer between the layers and switchable between states including a first state and a second state in which electrical resistance is higher than in the first state, and a circuit executing a write process. The circuit is configured to, in the process to switch the memory layer from the second to the first state, alternately apply to the second layer a first voltage having positive polarity and a second voltage having negative polarity, an absolute value of the second voltage being larger than the first voltage, and in the process to switch the memory layer from the first to the second state, alternately apply to the second layer a third voltage having negative polarity and a fourth voltage having positive polarity, an absolute value of the fourth voltage being larger than the third voltage.
