Storage device that carries out parallel operations in response to host commands and upon detection of an error condition in one operation, continues the other operation before notification of the error condition is transmitted to the host

摘要

A storage device includes a non-volatile storage, and a controller configured to carry out, in parallel, operations in response to a plurality of commands received from a host and queued in a command queue. When the controller detects an error in a first operation that is being carried out in response to a first command while the controller is in parallel carrying out a second operation in response to a second command, the controller continues to carry out the second operation until a predetermined condition is met while carrying out the second operation and, at that time when the predetermined condition is met, transmits an error event notification to the host.
