We report unusual gate current variations with gate bias and time in accumulation regime. Measurements and simulations show the importance of the time-dependent floating body potential in both partially and fully depleted SOI MOSFETs. These variations during front-gate voltage scan and the resulting transient gate current are discussed as a combination of several mechanisms such as capacitive coupling, SRH generation, band-to-band tunneling and impact ionization. The gate current behavior is important for EEPROMs and depends on the device geometry and operating conditions.
