A storage media characteristic is a statistic, heuristic, or other descriptor associated with an attribute of the solid-state storage media 110. A storage media characteristic for a set of storage cells may be substantially static or may be dynamic and change over time. A storage media characteristic, in one embodiment, includes or relates to a make, a model, a manufacturer, a product version, or the like for the solid-state storage device 102 and/or for the solid-state storage media 110. In another embodiment, a storage media characteristic describes an attribute or statistic for a set of particular storage cells, such as a program/erase cycle count for the set of storage cells, a read count for the set of storage cells, a retention time since a previous write for the set of storage cells, an error statistic for the set of storage cells, or the like. A storage media characteristic, in a further embodiment, may include or relate to an environmental condition or a use of the solid-state storage device 102 and/or of the solid-state storage media 110, such as a temperature, a use case (e.g. a cache use case, an archival use case, a server use case, an enterprise use case, a consumer use case, etc.), or the like.
A storage media characteristic for a set of storage cells affects or informs the determination of a configuration parameter for the set of storage cells. In one embodiment, the storage media characteristics include a program/erase cycle count for a set of storage cells. In another embodiment, the storage media characteristics include a read count for a set of storage cells. The storage media characteristics, in a further embodiment, include a retention time since a previous write for a set of storage cells. In an additional embodiment, the storage media characteristics include a temperature for a set of storage cells. The storage media characteristics, in certain embodiments, include a use case for a set of storage cells. In another embodiment, the storage media characteristics include an error statistic for a set of storage cells, such as an UBER or the like. In a further embodiment, the storage media characteristic may include previous or historical configuration parameters for a set of storage cells, configuration parameters or storage media characteristics for other sets of storage cells, or the like.
Other storage media characteristics, such as a program/erase cycle counts, read counts, retention times, temperatures, use cases, error statistics, and the like may be dynamic and change frequently.
The media characteristic module 502, in certain embodiments, manages the collection of and/or maintenance of storage media characteristics. The media characteristic module 502 may maintain storage media characteristics in and/or retrieve storage media characteristics from a storage media characteristic repository. One example of a storage media characteristic repository is described in greater detail below with regard to FIGS. 7A and 7B. The media characteristic module 502, in certain embodiments, references, determines, and/or manages storage media characteristics for several different sets of storage cells, such as each storage media region or storage media division of the solid-state storage device 102. A storage media region may include an erase block (logical or physical), a page, a logical page, an ECC chunk, a division within a page, a die, a die plane, a chip, or the like.
