A memory device may be configured to leverage memory resources of a host computing device to efficiently transition between different power states. In some embodiments, the memory device stores resume data within a host memory buffer (HMB) before transitioning to a low-power state, and uses the resume data stored within the HMB to resume operation from the low-power state. The memory device may be configured to pre-populate the HMB with resume data prior to transitioning to the low-power state. In some embodiments, the disclosed memory device is configured to gradually resume from the low-power state, which may comprise resuming services of the memory device in the order such services are required during the resume process.
