Abstract
A method for operating a memory includes receiving an input data set, saving a first level error correcting code ECC for the data in the input data set, saving second level ECCs for a plurality of second level groups of the data in the data set, storing the data set in the memory, and testing the data set to determine whether to use the first level ECC or the second level ECCs. The method includes, if the first level ECC is used, storing a flag enabling use of the first level ECC, else if the second level ECCs are used, storing a flag enabling use of the second level ECCs. The method includes storing the second level ECCs in a replacement ECC memory, and storing a pointer indicating locations of the second level ECCs in the replacement ECC memory.
