<P>A reconfigurable field-effect transistor (RFET) with memory functionality is proposed as a new high-density synaptic device capable of exclusive NOR (XNOR) operation for a binary neural network (BNN). A RFET with three gates is used in this letter, consisting of two program gates (PGs) electrically connected to each other and a control gate (CG) between the PGs. By changing the polarity of the PG bias or the polarity of the charge trapped in Si<SUB>3</SUB>N<SUB>4</SUB> layer on the PGs, the RFET operates as an <TEX>${n}$</TEX>- or a <TEX>${p}$</TEX>-MOSFET having a CG as a switching gate. The XNOR operation is successfully demonstrated in a fabricated RFET. The on/off current ratio (the ratio of 1 to 0 in the result of the XNOR operation) is ~10<SUP>4</SUP> and the current is ~1 nA/ <TEX>$\mu \text{m}$</TEX>. Using a RFET as a synaptic device for a BNN is efficient in terms of the area (~8F<SUP>2</SUP>/synapse) because XNOR operation can be performed using only one RFET.</P>
