Abstract

The invention discloses a voltage refreshing device and a storage system. The voltage refreshing device comprises a pulse generation unit, a logical unit and a control unit, wherein the pulse generation unit is used for counting input clock signals according to the input standby state signal and outputting the obtained pulse control signal in a preset duty ratio to the logical unit and the control unit; the logical unit is used for generating a first enable signal which is output to a voltage generating circuit according to the input operating state signal and the input pulse control signal; the control unit is used for controlling a path where the voltage generating circuit outputs a voltage signal to an output end of the voltage refreshing device according to the input pulse control signal so as to guarantee that the voltage refreshing device outputs a constant fixed voltage. The power consumption of the voltage generating circuit in a standby state can be reduced, so that the voltage refreshing device can be suitable for low-power consumption application. Moreover, when the voltage generating circuit is switched into an operating state, the fixed voltage is rapidly output, and the voltage refreshing device is suitable for high-speed application.
