Abstract
Apparatuses, systems, methods, and computer program products are disclosed for configuring storage cells. A method includes determining a usage history for a set of storage cells of a solid-state storage medium. A method includes adjusting a voltage threshold for a set of storage cells by an amount based at least in part on a usage history. A method includes configuring a set of storage cells to use an adjusted voltage threshold.
Claims20
A method comprising:
- determining a usage history for a set of storage cells of a solid-state storage medium;
- adjusting a voltage threshold for the set of storage cells by an amount based at least in part on the usage history;
- and
- configuring the set of storage cells to use the adjusted voltage threshold.
1 more element
An apparatus comprising:
- a data set read module configured to detect a shift in a read voltage level past a read voltage threshold for a set of memory cells of a non-volatile memory medium;
- an adjustment module configured to, in response to the shift in the read voltage level, adjust a read voltage threshold for the set of memory cells by an amount based at least in part on one or more characteristics of the set of memory cells;
- and
- a read voltage module configured to configure the set of memory cells to use the adjusted read voltage threshold.
1 more element
An apparatus comprising:
- means for determining a number of program and erase cycles for a set of storage cells of a solid-state storage medium;
- and
- means for compensating for a change in read voltage levels for the set of storage cells based at least in part on the number of program and erase cycles.
