ABSTRACT:
A current-direction sense-amplifier circuit for amplifying data signal read out from a bit-line of memory cells is disclosed. The current-direction sense-amplifier circuit includes two positive feedback loop circuits coupled each other. The first positive feedback loop circuit which having a data input terminal for receiving the data signal, first output node, and second output node for amplifying a differential voltage between a voltage of the first output node and a voltage of the second output node. The second positive feedback loop circuits being coupled with the first positive feedback loop circuit at the first output node and second output node of node so as to enlarge the loop voltage gain and make the increment and the decrement of voltage swing more symmetrical.
