Abstract
A redundancy circuit (300) for generating a standard column access signal (STD) and a redundant column access signal (RED) is disclosed. A modified NOR-type decoder (310) determines if an applied address is the same as a defective address. In the event the applied address is the same as the defective address, a match indication is activated. In the event the applied address is different than the defective address, a no match indication is generated. The match indication activates the RED signal and the no match indication activates the STD signal, according to the timing of a 'mimic' circuit (312). The mimic circuit (312) emulates the slowest resolution of the match/no match indication by the modified NOR-type decoder (310).
