SRAM undershoot and IBIS models

IBISgurus:

In many SRAM datasheets, they have a 'Undershoot Voltage' spec that looks
like this:

     Vih________
                \
                 \
                  \ /\ ___________ Vss
                   \ / \ /
                    \ / \/
                ---------------------
                     |\ /|
                     | \/ |
                --------------------- Vss - 1.0V
                ---->| |<---
                 
                "20% of Cycle time"
                
Question:
---------
1) Can this be modeled in IBIS ? if yes, by using which keyword ?

If the cool ASCII drawing got messed up by your mail system, refer to
Motorola SRAM databook for MCM63F737K/MCM63F819K.
