ABSTRACT:
A nonvolatile memory having a memory array including a plurality of data cells and a read circuit. The read circuit includes a plurality of sense amplifiers, each connected to a respective array branch to be connected to the data cells. The nonvolatile memory also includes a reference generating circuit including a single reference cell arranged outside the memory array and generates a reference signal. The reference generating circuit includes a plurality of reference branches, each connected to a respective sense amplifier, and circuits interposed between the reference cell and the reference branches to supply the reference branches with a signal based on the reference signal.
