Abstract
An address path circuit with a row redundant scheme may include an address buffer for buffering an external address to output an internal address, a command buffer for buffering a plurality of external commands, a pre-latch unit for pre-latching the internal address from the address buffer using a specific one of the commands buffered by the command buffer to output a pre-latched internal address, a detector for detecting whether the pre-latched internal address from the pre-latch unit is a repaired address or normal address and outputting one or more detection signals as a result of the detection, an address latch unit for latching the internal address from the address buffer synchronously with a buffered clock to output a latched internal address, and a global address generator for receiving the detection signals from the detector and the latched internal address from the address latch unit and generating a global row address.
