Abstract
Unit cells of silicon-oxide-nitride-oxide-silicon (SONOS) memory devices are provided. The unit cells include an integrated circuit substrate and a SONOS memory cell on the integrated circuit substrate. The SONOS memory cell includes a source region, a drain region and a gate contact. The integrated circuit substrate defines a trench between the source and drain regions and the gate contact is provided in the trench. A floor of the trench extends further into the integrated circuit substrate than lower surfaces of the source and drain regions. Related methods of fabricating SONOS memory cells are also provided.
