Abstract: The read circuit (30) has an array branch (31) connected to an array cell (33), and a reference branch (32) connected to a reference cell (37); the array branch (31) presents an array load transistor (42) interposed between a supply line (36) and the array cell (33), and the reference branch (32) presents a reference load transistor (43) interposed between the supply line (36) and the reference cell (37); and the array and reference load transistors (42, 43) form a current mirror wherein the array load transistor (42) is diode-connected and presents a first predetermined channel width/length ratio (W1/L1), and the reference load transistor (43) presents a second predetermined channel width/length ratio (W2/L2) N times greater than the first ratio (W1/L1), so that the current (I'M) flowing in the array cell (33) is supplied, amplified, to the reference branch.
