ABSTRACT:
The present invention provides a sense amplifier with high speed and stable sensing capabilities under a low supplying voltage. In accordance with the present invention, there is disclosed a sense amplifier comprising: a voltage level shifter for shifting a voltage level of data from a memory cell in response to a sense amplifier enable signal; a current mirror type sense amplifying stage for amplifying the level-shifted data from the voltage level shifter to full range in response to the sense amplifier enable signal; and a driver means for driving the amplified data from the current mirror type sense amplifying stage.
