Abstract
An address signal storage circuit of a data repair controller is disclosed including: a level stabilizer for stabilizing a level of an input signal to a constant level by a level control signal applied from the exterior according to the connection and disconnection of a fuse; a control signal generator for generating first and second control signals by a signal stabilized from the level stabilizer; and a signal storage portion for generating either a signal of a constant level by the first control signal generated from the control signal generator after disabled by a driving control signal applied from the exterior, or an inversion signal of the signal generated when disabled by storing an address signal of a prescribed level by the first and second control signals after enabled by the driving control signal.
