Propagation Delay of Traces on PCBs
100MHz can work after 8" of length (need to make sure timings are affordable, like the delay for data after giving #RD signal). As long as you keep traces in same layer with affordable trace impedance and a series termination near to strong driver, it will work.- ephrem79

Propagation Delay of Traces on PCBs
I think there is some confusion. While talking about digital signals, you need to consider the rise time of control signals/data signals (whichever is faster) for wavelength calculation. What you need to make sure is your reflections should be settled within the rise time.- ephrem79
