Configuration parameter management using a configuration tool

An apparatus comprising:

• an initialization module configured to initialize a value for a configuration parameter for a set of cells of a non-volatile memory medium, based on a predetermined model for the set of cells;
• an update module configured to adjust the configuration parameter using an existing function of the non-volatile memory medium in response to a trigger, the existing function using the initialized value to adjust the configuration parameter;
• and
• an access module configured to access the set of storage cells using the adjusted configuration parameter.

A system comprising:

• a non-volatile recording device comprising a non-volatile recording medium;
• and
• a controller for the non-volatile recording device, the controller
• establishing an initial read voltage threshold for an erase block of the non-volatile recording medium, based on one or more characteristics for the same erase block,
• setting the read voltage threshold by triggering a configuration tool of the non-volatile recording medium in response to a threshold being satisfied, and
• accessing the erase block using the set read voltage threshold.

An apparatus comprising:

• a trigger module configured to determine that a trigger has occurred for a region of a non-volatile storage medium;
• an update module configured to determine a read voltage threshold using a read voltage search function of the non-volatile storage medium in response to the trigger;
• and
• an access module configured to access the region of the non-volatile storage medium using the determined read voltage threshold.
