Assuming that Tbus is of the same order of magnitude as Tv, we would have:

This is generally similar in form to the interleaved case, with a minor adjustment for the Tbus, Tv distinction.
EXAMPLE 6.7 COMPUTING TLINE ACCESS
Assume we have Ta = 200 ns, Tc = 150 ns, Tv = 40 ns, Tbus = 50 ns, L = 8, and v = 4.
We would have the following time relationship:

which we compute as:

The final case is an interleaved memory consisting of modules with fast sequential page mode. Assume

That is, that memory to processor transfers are determined by the bus time (Tbus), not the interleaved page time.
Here, the line access is approximately:
