Error correcting

One or more computer-readable media comprising computer-executable instructions that, when executed:

• receive from a single, integrated memory current and previous iterations of Log Likelihood Ratio (“LLR”) parameters for a current iteration of a Low-Density Parity-Check code (“LDPC code”) error-correcting process;
• perform an LDPC code error-correcting algorithm using the current and previous iterations of LLR parameters;
• overwrite the previous iteration of LLR parameters with a now-current iteration of LLR parameters and treat the current iteration of LLR parameters as a now-previous iteration of LLR parameters;
• after overwrite of the previous iteration of LLR parameters, receive both the now-current and the now-previous iterations of LLR parameters for the now-current iteration of the LDPC code error-correcting process from the single, integrated memory;
• and
• perform the LDPC code error-correcting algorithm using the now-current and the now-previous iterations of LLR parameters.
