Abstract
A device including a load connected by a selection circuit to a number of bit lines, and a load connected to a reference cell, for detecting the current in the selected bit line and in the reference cell. The load connected to the bit lines comprises a transistor, and the reference load comprises two current paths, each formed by one transistor. One of the two transistors is diode-connected, and the other is switchable by a switching network connected to the gate terminal of the respective transistor, for turning it off when only one reference current path is to be enabled, and for diode-connecting it when both the reference current paths are to be enabled.
