ABSTRACT:
A static sense amplifier, particularly for non-volatile memories, is disclosed. The static sense amplifier includes a differential stage having non-inverting and inverting input terminals respectively connected to a reference branch and to a matrix branch of a matrix of memory cells, and a feedback loop coupled between the output of the differential stage and the inverting input terminal thereof. The feedback loop includes a pull-up device having a control terminal driven by the output of the differential stage and a terminal connected to the inverting input terminal of the differential stage.
