SOLID STATE DRIVE WITH SELF-REFRESH POWER-SAVING MODE

摘要

A storage device (28) includes a non-volatile memory (32), a volatile memory (40) and a controller (36). The volatile memory supports a normal mode and a self-refresh mode. The controller is configured to store data for a host (24) in the non-volatile memory while using the volatile memory in the normal mode and, in response to receiving a power-down command from the host, to deactivate at least part of the storage device and to switch the volatile memory from the normal mode to the self-refresh mode.
