Systems and methods for host system memory translation are disclosed. The memory system may send a logical-to-physical address translation table to the host system. Thereafter, the host system may send commands that include a logical address and a physical address (with the host system using the logical-to-physical address translation table previously sent to generate the physical address). After sending the table to the host system, the memory system may monitor changes in the table, and record these changes in an update table. The memory system may use the update table in determining whether to accept or reject the physical address sent from the host system in processing the host system command. In response to determining to reject the physical address, the memory system may internally generate the physical address using the logical address sent from the host system and a logical-to-physical address translation table resident in the memory system.

System and method for host system memory translation

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.
