Smart host stream release

Abstract

Aspects of a storage device are provided for intelligently releasing a stream. The storage device includes one or more non-volatile memories, and one or more controllers operable to release a stream in the storage device. In particular, the controller(s) may, individually or in combination, obtain a stream release request from a host device, the stream release request indicating a stream identifier and including an indication of whether to deallocate a stream associated with the stream identifier, and deallocate, in response to the stream release request and based on the indication, a plurality of logical addresses associated with the stream from corresponding physical addresses associated with the one or more non-volatile memories. The deallocation may be performed without waiting for dataset management commands for deallocation from the host. Thus, reduced performance impact and latency may be achieved in the process of deallocating logical address ranges associated with a released stream identifier.
