Effect of interface states on 1T-FBRAM cell retention
In this work, the retention of 1T-RAM UTBOX SOI devices is investigated. It is found that the interface defects at 0.3eV below the Si conduction band are responsible for the short retention times. The measured retention time and kinetics are reproduced by a model assuming hole generation via interface states.
