Abstract
A redundancy circuit for a NAND flash memory device reduces a test time and production time of the device, by performing a redundancy operation through a repair select unit using a cam cell. In addition, the redundancy circuit employs a repair method using a redundancy cam which can perform the repair operation much faster than a general repair method using fuse cutting.
