A not so speedy response as I've been busy.
Anyway, running the prog above in a loopI get this:
Ch1 = yellow = Data line (CD6 i think)
Ch2 = blue = WR
Ch3 = RAS
CH4 = CAS
CAS and RAS might be the other way round, but clearly most of the second mem cycles are not used.
Not many write cycles either.
And zoomed with the cursors on a few places:
The point I was making earlier is there never seems to be a transition on the 250ns mark for the data lines, And I checked a few lines. If it was interleaved then there should be changes on the 250ns points relative to the regular 500ns timings.
