Abstract
Described herein are methods and devices for controlling power loss. For one embodiment, a method includes issuing a controlled power off command with a controller. The method includes determining whether a memory device is performing a background operation. The method includes safely suspending the background operation or completing the background operation if the memory device is performing the background operation. The method includes safely removing a supply power.
Claims19
A non-volatile memory (NVM) device, comprising:
- a NVM array to store data;
- a command interface coupled to the NVM array, the command interface to receive a controlled power off command from a controller;
- and
- a status register unit coupled to the NVM array, the status register unit to store information indicating whether the NVM device is implementing a background operation, the NVM device to safely suspend the background operation or to complete the background operation prior to loss of a supply power if the NVM device is implementing the background operation.

A data processing device, comprising:
- a processing unit having one or more processor cores;
- and
- system memory coupled to the processing unit, the system memory having a non-volatile memory (NVM) device comprising:
- a NVM array to store data;
- a command interface coupled to the NVM array, the command interface to receive a controlled power off command from the processing unit;
- a status register unit coupled to the NVM array, the status register unit to store information indicating whether the NVM device is implementing a background operation, the NVM device to safely suspend the background operation or to complete the background operation prior to loss of a supply power if the NVM device is implementing the background operation.
