There is something in lmbench which can sort of do what you want. If what you want is to touch a lot of memory and time how long that takes, you can do this
lmdd opat=1 bs=200m count=1
that will allocate a 200m buffer, bzero it, and then put a pattern in it once.
You may want to run over the memory several times, then use a count=5 etc.
