Abstract
A memory system having a memory block and a memory controller in communication with the memory block. The memory controller is configured to: decode codewords in the memory block; determine failed codewords based on one or more parity checks including a chipkill parity; and turbo-decode the failed codewords using at least two decoders in a feedback loop with adders prior to each decoder for scaling soft decode information prior to subsequent decoding of the failed codewords.
