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. 本发明公开了种存储设备(28)，该存储设备包括非易失性存储器(32)、易失性存储器(40)和控制器(36)。易失性存储器支持正常模式和自刷新模式。控制器被配置为当在所述正常模式使用所述易失性存储器时将用于主机(24)的数据存储在所述非易失性存储器中，并响应于从所述主机接收到掉电命令来去激活所述存储设备的至少部分以及将所述易失性存储器从所述正常模式切换到所述自刷新模式。
