A method includes entering a hibernation mode in a data storage device with a controller, a non-volatile memory, and a volatile memory having a first portion and a second portion. The hibernation mode is entered by copying, to the second portion, data that is in the first portion and that is flagged to remain available at the volatile memory during the hibernation mode, and powering off the first portion while maintaining power to the second portion.

Systems and methods of performing a data save operation

A method includes determining, based on an indication from a host device operatively coupled to a data storage device that includes a controller, a non-volatile memory including a hibernate area, a volatile memory, a non-volatile memory interface, and a volatile memory interface, that the data storage device is to enter a low-power state. The method includes, in response to determining that the data storage device is to enter a low-power state, performing a data save operation. The data save operation bypasses the non-volatile memory interface and the volatile memory interface and copies data from the volatile memory of the data storage device to the hibernate area of the non-volatile memory of the data storage device.

A method may be performed by an electronic device coupled to a volatile system memory. The method includes entering a hibernation mode of the electronic device, where in the hibernation mode, the volatile system memory is powered off. The method further includes detecting a triggering event and, in response to detecting the triggering event, exiting the hibernation mode. While exiting the hibernation mode, the volatile system memory is powered and a pre-hibernation state of the volatile system memory is restored.

Systems and methods of exiting hibernation in response to a triggering event

A method may be performed in a data storage device that includes a controller, a non-volatile memory, and a volatile memory. The method includes loading a first portion of stored data from the non-volatile memory to the volatile memory according to one or more load priority indicators accessible to the controller. The method further includes, in response to completion of the loading of the first portion of the stored data to the volatile memory and prior to completion of loading a second portion of the stored data to the volatile memory, sending a signal to indicate to a host device operatively coupled to the data storage device that the volatile memory is ready for use by the host device.

Systems and methods of loading data from a non-volatile memory to a volatile memory

A storage device with a memory, a controller, a storage device interface and a host interface, and a method of data transfer to and from a storage device are provided. The storage device is operative to connect with a host device and the storage device interface is operative to couple with an add-on memory. When the host interface is connected to a host device, the controller is configured to receive a data transfer command specifying a memory address from the host interface; and if the memory address is beyond the address space of the memory, to route the data transfer command to the storage device interface for access to the add-on memory. The address space of the memory and an address space of the add-on memory are addressed as one integral address space transparently to the host.
