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.
