Memory Access

Question

In Numerical answer type questions,  when we have to consider simultaneous memory access and when we have to use hierarchical memory access model?  How to know it?

Comments

I think unless mentioned you should consider hierarchical because that is what is used in modern/most architectures.

@Rishabh Jain,  please check these links.. Here they used simultaneous access and nothing was mentioned..

@ankit go through the comments on respective questions, you'll know why they considered simultaneous there though you'll probably have to spend some time on it. Default convention is to use hierarchical but subtle language used in questions could hint what we actually need to use.
