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 translation: 存储模块被配置为确定固态存储介质的存储分区的健康度量。 健康度量可以包括因素的组合，包括但不限于：磨损水平，性能（例如，程序时间，擦除时间等），错误率等。 磨损水平模块可以配置存储操作以降低具有差的健康度量和/或健康度量的存储部门的磨损率，其比其他存储部门更快地劣化。 降低磨损率可能包括推迟修饰操作，延迟存储操作的使用，暂时停止存储部门等。 存储部门可以以正常使用率被恢复使用，以响应确定存储介质的其他部分已经磨损到它们表现出类似的健康和/或可靠性特征的点。

Abstract: A memory device includes a memory array with a plurality of memory elements. Each memory element is configured to store data. The device includes an input/output (I/O) buffer coupled to the memory array. The I/O buffer is configured to receive data from an I/O interface of a memory device controller and write the data to the memory array. The device includes a memory control manager coupled to the memory array. The memory control manager is configured to pause a program operation to the memory array in response to receiving a pause command. The memory control manager is also configured to resume the program operation in response to receiving a resume command.

Abstract: An apparatus, system, and method are disclosed for managing erase operations for a data storage medium. A method includes determining whether a use threshold for one or more non-volatile storage cells is satisfied. A method includes performing a default erase operation for the one or more storage cells in response to determining that the use threshold is not satisfied. A method includes performing an extended erase operation for the one or more storage cells in response to determining that the use threshold is satisfied. An extended erase operation may include a greater number of erase pulse iterations than a default erase operation.

Abstract: An apparatus includes an input/output (I/O) interface configured to couple a controller to an I/O buffer of a memory device. The controller includes an erase module coupled to the I/O interface. The erase module is configured to issue an instruction to the memory device to erase data from the memory device. The controller includes an erase suspend module coupled to the I/O interface. The erase suspend module is configured to determine that an erase operation executing within the electronic memory device satisfies a suspend policy in response to receiving a memory access request to perform an operation on the memory device on which the erase operation is executing. The erase suspend module is further configured to issue a suspend command to the memory device to suspend the erase operation.
