Semiconductor device and control method thereof

A semiconductor device in which a plurality of semiconductor chips laminated on a substrate are electrically connected via a plurality of through electrodes penetrating in a lamination direction, wherein

• the plurality of semiconductor chips include first semiconductor chips each having one or more memory blocks and a decoder and a second semiconductor chip having a logic circuit that controls operations of the memory blocks,
• the memory blocks includes a plurality of first memory blocks and a plurality of second memory blocks,
• the logic circuit includes one selection circuit connected to the decoder of all the first semiconductor chips and configured to select addresses of a substituted first memory block among the first memory blocks and a substituting second memory block among the first memory blocks, inputting and outputting of the substituted first memory block being turned off, and inputting and outputting of the substituting second memory block being turned on instead of the substituted first memory block, and
• the addresses of the substituted first memory block and the substituting second memory block are each common to all the first semiconductor chips.
