Abstract
The read circuit has an array branch connected to an array cell, and a reference branch connected to a reference cell; the array branch presents an array load transistor interposed between a supply line and the array cell, and the reference branch presents a reference load transistor interposed between the supply line and the reference cell; and the array and reference load transistors form a current mirror wherein the array load transistor is diode-connected and presents a first predetermined channel width/length ratio, and the reference load transistor presents a second predetermined channel width/length ratio N times greater than the first ratio, so that the current flowing in the array cell is supplied, amplified, to the reference branch.
