A 2-bit FinFET flash memory cell capable of storing 2 bits and a method of
forming the same are provided. The memory cell includes a semiconductor
fin on a top surface of a substrate, a gate insulation film on the top
surface and sidewalls of a channel section of the semiconductor fin, a
gate electrode on the gate insulation film, and two charge-trapping
regions along opposite sides of the gate electrode, wherein each
charge-trapping region is separated from the gate electrode and the
semiconductor fin by a tunneling layer. The memory cell further includes
a protective layer on the charge-trapping regions. Each of the two
charge-trapping regions is capable of storing one bit. The memory cell
can be operated by applying different bias voltages to the source, the
drain, and the gate of the memory cell.
