Abstract
A sense amplifier for a flash memory is disclosed which includes a pre-charging circuit, a first capacitor, a first inverter, and a first transmission gate connected in parallel with the first inverter, the pre-charging circuit is connectable to a reference voltage node, and is able to pre-charge a word line, of the flash memory, via the reference voltage node, a potential of the reference voltage node remains unchanged after the pre-charging is completed; a potential of the reference voltage node is adjustable according to a state of the flash memory until an output voltage of the first inverter changes; the first capacitor has a first end connected to the reference voltage node, a second end connected to an input of the first inverter and a first end of the first transmission gate; an output of the first inverter is connected to a second end of the first transmission gate.
