System and method of error correction of control data at a memory device
A method includes initiating a compression operation to compress data to be stored in a group of storage elements at a memory device that includes an error correction coding (ECC) engine. The method includes selecting one of a first mode of the ECC engine to generate a first number of parity bits and a second mode of the ECC engine to generate a second number of parity bits based on an extent of compression of the data. The method also includes encoding the compressed data to generate parity bits corresponding to the compressed data and storing the compressed data and the parity bits to the group of storage elements according to a page format that includes a data portion and a parity portion. The compressed data is stored in the data portion and at least some of the parity bits are stored in the parity portion.
