On the interface recovery of SNOI devices during programming-erasing cycles

In this paper, we study the interface traps during program/erase (P/E) cycles. By using charge pumping measurement, the charge pumping currents (ICP) of the serial P/E cycled states are compared to the initial one. The ICP decreases after the programmed operation under a constant temperature within 5 P/E cycles. The observation on the recovery of the interface states has been attributed to the hot electron injection stress.
