A solid state storage device receives a device sleep signal and a power signal from a host. The solid state storage device includes a control chip, a sleep control circuit, and a regulator. If the device sleep signal is activated, the control chip temporarily stores a system parameter into a flash memory module and then generates an acknowledge signal. The sleep control circuit receives the power signal, the device sleep signal and the acknowledge signal. If both of the device sleep signal and the acknowledge signal are activated, the sleep control circuit generates a disable state and a wake-up state. Moreover, if the power signal is received by the regulator and the sleep control circuit generates the disable state, the regulator stops providing a supply voltage to the control chip, so that the solid state storage device enters a sleep mode.
