A Pb5Ge3O11 metal-ferroelectric-metal-oxide-silicon memory transistor has b
een fabricated. The device showed a memory window of about 2 V. The memory
window was almost saturated at the operation voltage of 2 V. The "off" stat
e drain current (I-D) at V-D of 0.1 V and V-G of 0.5 V is about 1x10(-8) A.
The "on" state drain current (I-D) at V-D of 0.1 V and V-G of 0.5 V is abo
ut 1x10(-6) A, which is 100 times high than that of off state. (C) 2001 Ame
