Abstract
A coding device, such as a memory device or communication system, comprising encoder circuitry configured to encode data into inner codewords and multiple-strength Reed-Solomon outer codewords, the Reed-Solomon outer codewords including weak strength, mid-strength, and strong strength. The strength of the codewords can be varied by changing at least one of the code length N, data length K, parity length R, symbol size S and code rate K/N.
