Content
In one embodiment, a manufacturer of the solid-state storage media 110 provides a command or procedure to adjust a read voltage threshold for a predefined grouping of storage cells, such as a chip, physical erase block, physical page, or a die. In a further embodiment, the persistence module 410 stores read voltage thresholds for sub-groupings of storage cells that are smaller than the predefined groupings of storage cells for which the adjustment module 408 can make adjustments using the manufacturer provided command or procedure. The adjustment module 408 may then, in another embodiment, readjust the read voltage threshold when a data set is read from a sub-grouping based on the read voltage thresholds that the persistence module 410 stores. Examples of sub-groupings may include PEBs, pages, ECC chunks, or other physical or logical divisions of a grouping of storage cells.
