Abstract
A sense amplifier circuit is divided into a plurality of sense amplifier groups. The plurality of sense amplifier groups are each further divided into a plurality of sense units. A sense amplifier control circuit is configured to sequentially select the plurality of sense amplifier groups according to a physical address, and to sequentially select the plurality of sense units included in a selected sense amplifier group. The sense amplifier control circuit is configured to, when there is a defect related to a selected sense unit in a selected first sense amplifier group, select, in place of the first sense amplifier group, a sense unit included in a second sense amplifier group selected following after the first sense amplifier group. 139463
