Abstract: A power loss condition is detected that affects volatile data that is cached in preparation for storage in a non-volatile, solid-state memory device. The volatile cached data is stored in an over-provisioned portion of the non-volatile, solid-state memory device in response to the power loss condition.

Abstract: In general, this disclosure relates to garbage collection in a storage device. Aspects of this disclosure describe techniques to identify one or more candidate memory storage blocks that should be recycled during garbage collection. The one or more candidate memory storage blocks may be identified based at least on monitored soft metrics of the candidate memory storage blocks. During garbage collection, the identified one or more candidate memory storage blocks may be recycled to free up storage space.

Abstract: In general, this disclosure relates to storage of logical blocks in a storage device. Aspects of this disclosure describe techniques to monitor the frequency of access of one or more logical blocks referenced by one or more logical block addresses. Based on the frequency of access, in non-limiting aspects of this disclosure, a controller may select one or more physical blocks of a common memory storage block. The storage device may store the logical blocks in the selected physical blocks.

Abstract: In general, this disclosure is directed to techniques for adjusting the timing of operations for a storage device. According to one aspect of the disclosure, a method includes receiving, with at least one device, a workload indicator. The method further includes adjusting, with the at least one device, an operation execution time for the storage device responsive to at least the workload indicator. In some examples, the workload indicator may include a host demand indicator. In additional examples, the workload indicator may include a resource utilization indicator. In further examples, the operation execution time may be one of a write operation execution time or a read operation execution time.

Abstract: A system can log data access activity to a memory array with a metadata module while the memory array is logically divided into multiple namespaces. A workload can be determined for each namespace by the metadata module and a metadata strategy can be created with the metadata module in view of the respective namespace workloads. A first metadata and second metadata may be generated for respective first and second user-generated data for storage into a first namespace of the multiple namespaces. The first metadata can be compressed with a compression level prescribed by the metadata strategy in response to a detected or predicted workload to the first namespace before the first metadata, second metadata, first user-generated data, and second user-generated data are each stored in the first namespace.

Abstract: Completion times of data storage operations targeted to a non-volatile, solid-state memory device are measured. Wear of the memory device is estimated using the measured completion times, and life cycle management operations are performed to affect subsequent wear of the memory device in accordance with the estimated wear. The life cycle management may include operations such as wear leveling, predicting an end of service life of the memory device, and removing worn blocks of the memory device from service.

Abstract: A first write request that is associated with a first logical address is received via a collection of write requests targeted to a non-volatile, solid state memory. It is determined whether the logical address is related to logical addresses of one or more other write requests of the collection that are not proximately ordered with the first write request in the collection. In response to this determination, the first write request and the one or more other write requests are written together to the memory.
