This is a phenomena associated with the gate thickness of a
transistor. When the thickness of oxide is very small there
exists a possibilty that electrons pass directly between
source and gate. This is a seond order effect and limits
the scaling down of transistor size.

How can you model a SRAM at RTL Level?
Calculate rise delay of a 3-input NAND gate driving a 3-input NOR gate through a 6mm long and 0.45m wide metal wire with sheet resistance R = 0.065 / and Cpermicron= 0.25 fF/m. The resistance and capacitance of the unit NMOS are 6.5k and 2.5fF. Use a 3 segment -model for the wire. Consider PMOS and NMOS size of reference inverter as 2 and 1 respectively. Use appropriate sizing for the NAND and NOR gate.
