Abstract
A selection decoder controls levels of a plurality of selection signals based on an address bit having at least one or more bits. A memory module is selected when its corresponding selection signal is at an activated level, and data can be read and written therein. A failure determination unit determines whether or not the selection decoder is in a failed state based on the levels of the plurality of selection signals.
