Paragraph Number

120

Iteratively adjusting media parameters using a control loop module 410 may allow the configuration module 150 to tune media parameters for the non-volatile memory media 122 more effectively than it could by using the adjustment module 306 once. For example, in one embodiment, the error information may suggest a direction, but not a distance, for adjusting a read voltage threshold. Thus, the read voltage threshold may be over-adjusted or under-adjusted if the adjustment module 306 adjusts it once. However, a control loop module 410 may repeatedly determine error information and activate the adjustment module 306 to make successively finer adjustments to the read voltage threshold in order to satisfy an error criterion.
