ABSTRACT:
A data reading circuit comprising a first data line to which a first current signal having a first current value is supplied, a second data line to which a second current signal having a second current value is supplied, a current-voltage converter circuit connected between the first and second nodes for applying a first voltage potential difference, which corresponds to the difference between the first and second current values, between the first and the second nodes, a first node, a second node, a level shifting circuit connected between the first and second nodes and the third and fourth nodes for applying a second voltage potential difference, which is substantially equal to the first voltage potential difference in response to the same, between the third and fourth nodes and a feedback circuit connected between the first and second nodes and the third and fourth nodes for applying a third voltage potential difference, which is larger than the first voltage potential difference, between the first and second nodes in response to a first control signal.
