Patent ID: 7508717

Claim:
A reading circuit for reading semiconductor memory cells, adapted to be coupled to at least one memory cell and to at least one reference cell through a respective bit line, the reading circuit including: a pre-charge circuit for pre-charging the bit lines to a predefined voltage during a pre-charge phase of a reading operation on the memory cell; a biasing circuit for applying a bias to a respective control terminal of the memory cell and of the reference cell in response to an enabling signal; and for each bit line, an evaluation circuit for evaluating an electric quantity developing on the bit line as a consequence of the bias during an evaluation phase of the reading operation on the memory cell, an information content of the memory cell being determined on the basis of the electric quantity that develops on the bit lines, wherein the enabling signal is provided by the pre-charge circuit in response to an indication that the bit lines have reached the predefined voltage.
