ABSTRACT:
A method for controlling a semiconductor memory in which a mode register can be set in a burst mode. To set an operation mode in the burst mode, the semiconductor memory is changed first from the burst mode, through a power-down mode, to a standby mode of non-burst mode. Then the semiconductor memory is changed to a 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.
