Abstract
A sensitive amplifier and a storage device are provided, and the sensitive amplifier includes: a voltage clamp circuit which provides a stable reading voltage for the storage unit; a power switch circuit which cuts off power supply for the voltage clamp circuit when the voltage clamp circuit is not operating; a discharge circuit which discharges the voltage clamp circuit before the voltage clamp circuit operates; a pre-charge circuit which pre-charges the voltage clamp circuit when the voltage clamp circuit starts operating; and a current comparison circuit which is connected to an output of the voltage clamp circuit, compares the reading current with a reference current, and outputs a comparison result.
