ECC adjustment based on dynamic error information
A device includes a memory, an error correction code (ECC) decoder, and an ECC input adjuster. The ECC decoder is configured to perform a first decode operation to decode a first portion of a representation of data read from the memory based on one or more decode parameters and to perform a second decode operation to decode a second portion of the representation of data based on one or more adjusted decode parameters. The ECC input adjuster is configured to adjust one or more decode parameters to set the one or more adjusted decode parameters based on a count of bits of the first portion that are erroneous.
