Abstract
A redundancy circuit includes an address redundancy circuit block that compares column address information of a defective memory cell and an external input column address and outputs a redundancy column activation signal, and an input/output (IO) redundancy circuit block that, in response to IO fuse information, which is information about a sub-block where a column line of the defective memory cell is arranged, and the redundancy column activation signal, controls whether or not to activate a global IO line connected to an IO pad of the sub-block.
