Abstract
A redundancy circuit includes a selection control signal generation circuit and a column control circuit. The selection control signal generation circuit drives an internal node, which is initialized, to generate a selection control signal when a logic level of a latched address signal is different from a logic level of a fuse signal. The column control circuit buffers a pre-column selection signal based on the selection control signal to generate a column selection signal for execution of a column operation of cells or to generate a redundancy column selection signal for execution of the column operation of redundancy cells.
