摘要： A data storage device may consist of a non-volatile memory connected to a selection module. The non-volatile memory can have a rewritable in-place memory cell that has a read-write asymmetry. The selection module can dedicate a portion of the non-volatile memory to a data map that can be self-contained along with reactively and proactively altered by the selection module.

摘要： Method and apparatus for managing a solid state memory, such as but not limited to a NAND flash memory. In some embodiments, a storage device includes a non-volatile solid state memory and a control circuit configured to transfer user data between the memory and a host device. The control circuit maintains, in a local memory, a data structure indicative of measured readback error rates associated with memory locations in the memory in relation to erasure counts associated with the memory locations. The control circuit retires a subset of the memory locations identified by the data structure from further availability to store user data from the host device responsive to the measured readback error rates, and responsive to the erasure counts of said memory locations indicating the memory has reached an end of life (EOL) condition.

摘要： A data storage device may consist of a non-volatile memory having rewritable in-place memory cells each with a read-write asymmetry. The non-volatile memory can store boot data that is subsequently loaded by a selection module of the data storage device. The selection module may bypass a memory buffer of the data storage device to load the boot data.

摘要： Systems and methods for active power management are described. In one embodiment, the systems and methods include obtaining power dissipation metrics for a plurality of components under one or more operating scenarios, generating a reference dissipation model based on the power dissipation metrics of the plurality of components, and implementing the reference dissipation model in a storage system to make component scheduling decisions in relation to power management of the storage system. In some embodiments, the storage system includes any combination of a hard disk drive, a solid state drive, a hybrid drive, and a system of multiple storage drives.

摘要： Systems and methods for reducing read latency by storing a redundant copy of data are described. In one embodiment, the systems and methods include identifying data assigned to be written to a page of a storage device, storing the data in a page of a first die of the storage device, and saving at least one codeword from the data to a page of a second die. In some embodiments, the first die is associated with a first channel of the storage device and the second die is associated with a second channel of the storage device.

摘要： Systems and methods for limiting performance variation in a storage device are described. Storage devices receive work requests to perform one or more operations from other computing devices, such as a host computing device. Completing the work requests may take a response time. In some embodiments, if the response time of executing the work request exceeds a threshold, the storage device may assign additional computing resources to complete the work request.

摘要： A non-volatile memory may be resident in a data storage device. The non-volatile memory can consist of a rewritable in-place memory cell having a read-write asymmetry. The non-volatile memory may be divided into a first group of tiers with a selection module of the data storage device prior to adapting to an event by altering the non-volatile memory into a second group of tiers. The first and second groups of tiers being different.
