Abstract
A sense amplifying device includes a bit line bias voltage adjuster and a sense amplifying circuit. The bit line bias voltage adjuster receives a power voltage to be an operation voltage. The bit line bias voltage adjuster includes a first amplifier, a first transistor and a first current source. The first amplifier, based on the power voltage, generates an adjusted reference bit line voltage according to a reference bit line voltage and a feedback voltage. The first transistor receives the adjusted reference bit line voltage and generates the feedback voltage, wherein the first transistor is a native transistor. The sense amplifying circuit receives the power voltage to be the operation voltage, and generates a sensing result according to the adjusted reference bit line voltage.
