Abstract
A driver for a semiconductor memory may reduce an error in writing data in memory cells by adjusting the height and width of a spike current, when the memory cells in which data having the same level are written are arranged at different distances. In addition, the driver may reduce the error by controlling the amount of charges supplied to each of the memory cells that are arranged at different distances.
