摘要： Systems and methods are provided for obtaining and using nonvolatile memory (“NVM”) health information. Health information can include a variety of information associated with the performance and reliability of portions of an NVM device, such as the number of errors detected in a portion of NVM or the amount of time required to read from or program a portion of nonvolatile memory. During operation, address specific health information may be stored passively on a host device and provided as part of a command to a memory controller. The memory controller may extract the health information from the command and use the information to execute access requests. After an access request is completed, the memory controller can update the health information and transmit the information back to the host device.

摘要： This document generally describes systems, devices, methods, and techniques for obtaining debug information from a memory device. Debug information can include a variety of information associated with a memory device that can be used for debugging the device, such as a sequence of operations performed by the memory device and information regarding errors that have occurred (e.g., type of error, component of memory device associated with error). A memory device can be instructed by a host to obtain and provide debug information to the host. A memory device can be configured to obtain particular debug information using a variety of features, such as triggers. For instance, a memory device can use a trigger to collect debug information related to failed erase operations.

摘要： In a managed memory subsystem, information associated with the memory subsystem is copied from volatile memory in the memory subsystem to host system memory. The copying can be over a standard interface. Responsive to memory subsystem power up from a powered down state or power loss, the information is copied from the host system memory back to the volatile memory in the memory subsystem, where the information can be used by the memory subsystem to perform memory operations. Transferring information from host system memory to volatile memory in a memory subsystem is faster and more power efficient than transferring the same information from non-volatile memory to volatile memory in the memory subsystem.

摘要： A file system programs metadata on a non-volatile memory device. The metadata can include data associating files with ranges of logical block addresses. During a garbage collection process, the data can be used to determine portions of physical blocks of the non-volatile memory device that are associated with files that have been deleted. Using the programmed metadata during garbage collection results in erasure of larger portions of blocks and improved wear leveling.

摘要： Systems and methods are provided for improved communications in a nonvolatile memory (“NVM”) system. The system can toggle between multiple communications channels to provide point-to-point communications between a host device and NVM dies included in the system. The host device can toggle between multiple communications channels that extend to one or more memory controllers of the system, and the memory controllers can toggle between multiple communications channels that extend to the NVM dies. Power islands may be incorporated into the system to electrically isolate system components associated with inactive communications channels.

摘要： Systems and methods are disclosed for usage of a flag bit to suppress data transfer in a mass storage system having non-volatile memory (“NVM”). In some embodiments, a host of the system can issue queue-able trim commands by dispatching non-data transfer write commands to the NVM. In some embodiments, the host can track the read behavior of a particular application over a period of time. As a result, the host can maintain heuristics of logical sectors that are most frequently read together. The host can then notify the NVM to pre-fetch data that the application will most likely request at some point in the future. These notifications can take the form of non-data transfer read commands. Each non-data transfer read commands can include a flag bit that is set to indicate that no data transfer is desired.

摘要： Systems and methods are disclosed for mount-time reconciliation of data availability. During system boot-up, a non-volatile memory (“NVM”) driver can be enumerated, and an NVM driver mapping can be obtained. The NVM driver mapping can include the actual availability of LBAs in the NVM. A file system can then be mounted, and a file system allocation state can be generated. The file system allocation state can indicate the file system's view of the availability of LBAs. Subsequently, data availability reconciliation can be performed. That is, the file system allocation state and the NVM driver mapping can be overlaid and compared with one another in order to expose any discrepancies.
