摘要

This work investigates the behavior of Ultra Thin BOX (UTBOX) FDSOI devices used as a memory cell IT-DRAM (single transistor dynamic random access memory) at high temperatures through 2D numerical simulations. The minimum drain voltage for the onset of the bipolar junction transistor (BJT) effect (V_(Latch)) was obtained for various buried oxide thickness (t_(box)) and silicon film thickness (t_(Si)). The simulation results clearly show that, when temperature increases, the V(Latch), the sense margin current (ΔI_(SENSE)), the latch time (t_(Latch)) and the retention time decreases.
