A duration of time for a first idle state of a memory sub-system is determined, where the memory sub-system includes an active state and a second idle state. A first command is received to transition from the active state to the second idle state. In response to the first command, the memory sub-system is transitioned to the first idle state. The memory sub-system is transitioned from the first idle state to the second idle state in response to an expiration of the duration of time.

Management of power state transitions of a memory sub-system

A transitory idle state is established for a memory sub-system that can be transitioned from an active state to one or more idle states including the transitory idle state and a deep idle state. A power consumption metric and transition time for each idle state is identified. A transitional energy metric is determined for each idle state based on the corresponding power consumption metric transition time. An energy target time is determined for the transitory idle state. Based on the energy target time, an idle state optimization time is determined for the transitory idle state. The memory sub-system is maintained in the transitory idle state for a duration of the idle state optimization time.

Methods and systems configured to increment one or more counters, including read command total, write command total, total blocks written and read, and low read or write queue depth, when a read or write command is received. When a request for a total device busy time is received, a total device busy time is determined and provided using one or more of the counters and one or more corresponding timing factors.
