Configuration parameter management for non-volatile data storage
First Claim
Patent Images
1. A method comprising:
- programming and erasing blocks of a non-volatile storage medium such that variation of an erase dwell time for the blocks remains within a predetermined range;
grouping the blocks of the non-volatile storage medium based on retention times for the blocks; and
accessing at least one of the groups of blocks using a configuration parameter selected based on the grouping.

Abstract
Apparatuses, systems, and methods are disclosed for managing configuration parameters for non-volatile data storage. A control module is configured to limit erase dwell times for blocks of a non-volatile memory medium to satisfy a threshold. A block classification module is configured to group blocks of a non-volatile memory medium based on retention times for the blocks. A block access module is configured to access at least one group of blocks using a read voltage threshold selected based on a grouping.

17. A system comprising:
-
a non-volatile storage device comprising a non-volatile storage medium; and a controller for the non-volatile storage device, that manages variation of erase dwell times for blocks of the non-volatile storage medium, categorizes the blocks into groups based on retention times, and configures different groups to use different read voltage thresholds based on the retention times. - View Dependent Claims (18, 19, 20)
