detect a power interruption event,
track an amount of off-time for the persistent storage media after the detected power interruption event,
determine a voltage setting to use for an operation on the persistent storage media after power restoration based on the tracked amount of off-time, and
instruct application of the voltage setting after the power restoration.
2. The persistent storage media of claim 1 , wherein the logic is further to:
select a first value for the voltage setting if the tracked amount of off-time is less than a threshold; and
select a second value for the voltage setting if the tracked amount of off-time is greater than or equal to the threshold.
3. The persistent storage media of claim 1 , wherein the logic is further to:
select a first value for the voltage setting if the tracked amount of off-time is less than a configured time;
start a timer for a duration based on a difference between the configured time and the tracked amount of off-time; and
select a second value for the voltage setting after the timer expires.
4. The persistent storage media of claim 1 , wherein the logic is further to:
provide backup power to the logic to track the amount of off-time for the persistent storage media after the power interruption event.
5. The persistent storage media of claim 1 , wherein the persistent storage media comprises phase change memory.
6. The persistent storage media of claim 1 , wherein the logic coupled to the one or more substrates includes transistor channel regions that are positioned within the one or more substrates.

a controller;
persistent storage media communicatively coupled to the controller; and
logic communicatively coupled to the controller to:
detect a power interruption event,
track an amount of off-time for the persistent storage media after the detected power interruption event,
determine a voltage setting to use for an operation on the persistent storage media after power restoration based on the tracked amount of off-time, and
instruct application of the voltage setting after the power restoration.
8. The electronic storage system of claim 7 , wherein the logic is further to:
select a first value for the voltage setting if the tracked amount of off-time is less than a threshold; and
select a second value for the voltage setting if the tracked amount of off-time is greater than or equal to the threshold.
9. The electronic storage system of claim 7 , wherein the logic is further to:
select a first value for the voltage setting if the tracked amount of off-time is less than a configured time;
start a timer for a duration based on a difference between the configured time and the tracked amount of off-time; and
select a second value for the voltage setting after the timer expires.
10. The electronic storage system of claim 7 , further comprising:
a backup power source to provide power to the logic to track the amount of off-time for the persistent storage media after the power interruption event.
11. The electronic storage system of claim 10 , wherein one or more of the logic to track the amount of off-time and the backup power source comprises an energy storing capacitor.
12. The electronic storage system of claim 7 , wherein the persistent storage media comprises phase change memory.
13. A method of controlling persistent storage media, comprising:
detecting a power interruption event;
tracking an amount of off-time for the persistent storage media after the detected power interruption event;
determining a voltage setting to use for an operation on the persistent storage media after power restoration based on the tracked amount of off-time; and
instructing application of the voltage setting after the power restoration.
14. The method of claim 13 , further comprising:
selecting a first value for the voltage setting if the tracked amount of off-time is less than a threshold; and
selecting a second value for the voltage setting if the tracked amount of off-time is greater than or equal to the threshold.
15. The method of claim 13 , further comprising:
selecting a first value for the voltage setting if the tracked amount of off-time is less than a configured time;
starting a timer for a duration based on a difference between the configured time and the tracked amount of off-time; and
