Patent ID: 7196952

Claim:
A method of programming redundant columns for a multi-plane EEPROM, comprising the steps of: providing redundancy information in the form of two addresses for each defective column of the multi-plane EEPROM, where one address is the original address for the defective column and the other address is for corresponding fuse links that are programmed to access a redundant column instead of the defective column; from the address for the corresponding fuse links, providing redundant column word-line select (COL RED WL Select) signals to WL input terminals of a Column Redundancy CAM; from the address for the corresponding fuse links, providing column address decoded COL Address Decoded signals to decoded column address input terminals of the Column Redundancy CAM; and simultaneously programming all of the fuse links using the original address of the defective column such that the fuse links steer data designated for a defective column to a redundant, or replacement, column.
