Abstract: A current sense amplifier with dynamic pre-charge is proposed. There is a storage unit having a sense line, a voltage amplifier for generating a first output signal depending on the sense line, a first current mirror for generating a first current depending on the first output signal, a second current mirror for generating a second current depending on a reference storage unit, and a pre-charge circuit for generating a charge up signal on the sense line to pre-charge the sense line to an operation current level depending on the first output signal, the second current and a clock pulse so as to directly detect a data in the storage unit during detecting the sense line.
