Abstract: Apparatuses, systems, methods, and computer program products are disclosed for reduced level cell solid-state storage. A method includes determining that an erase block of a non-volatile storage device is to operate in a reduced level cell (RLC) mode. The non-volatile storage device may be configured to store at least three bits of data per storage cell. A method includes instructing the non-volatile storage device to program first and second pages of the erase block with data. A method includes instructing the non-volatile storage device to program a third page of the erase block with a predefined data pattern. Programming of a predefined data pattern may be configured to adjust which abodes of the erase block are available to represent stored user data values.

Abstract: A storage module is configured to determine a health metric of a storage division of a solid-state storage medium. The health metric may comprise a combination of factors, including, but not limited to: wear level, performance (e.g., program time, erase time, and the like), error rate, and the like. A wear level module may configure storage operations to reduce the wear rate of storage divisions having poor health metrics and/or heath metrics that are degrading more quickly than other storage divisions. Reducing wear rate may include deferring grooming operations, delaying use for storage operations, temporarily retiring the storage division, or the like. Storage divisions may be brought back into service at normal use rates in response determining that other portions of the storage media have been worn to the point that they exhibit similar health and/or reliability characteristics.

Abstract: An apparatus, system, and method are disclosed to manage non-volatile media. A media characteristic module is configured to determine media characteristics for non-volatile media. A configuration parameter module is configured to determine different configuration parameters for different storage cell abodes and/or for different groups of pages of the non-volatile media based on the determined media characteristics. A cell configuration module is configured to use the different configuration parameters for the different storage cell abodes and/or the different groups of pages of the non-volatile media.
