Abstract
A method for controlling a semiconductor memory in which mode register can be set in burst mode. To set an operation mode in burst mode, the semiconductor memory is changed first from the burst mode, through power-down mode, to standby mode of non-burst mode. Then the semiconductor memory is changed to mode register set mode to set the mode register when commands are input in the same predetermined sequence that is used in the non-burst mode.
