Abstract:
A semiconductor device includes a cell array having an upper segment and a lower segment which are classified according to refresh units. The semiconductor device includes a first repair controller configured to output a first repair signal for controlling a repair operation of the upper segment based on a fuse address, a row address, a second control signal, and selection address being at a first level, and generate a first control signal for controlling a repair operation of the lower segment based on the fuse address, the row address, and selection address.
