Hi,

I have gone through these two terms (Bank and Rank with regards to memory IC) and I still didn't get perfect clarity.

Can someone provide me a little write up explaining the above two terms with a neat example?

I would be really grateful. :)

Thanks.

It is often convenient to select/address memory locations a group at a time. Suppose you have a memory module consisting of several DRAM (or static RAM, or ROM) ICs. Each IC can consist of several memory blocks, each block containing several memory locations. According to the JEDEC definition in that link, each IC (or set of ICs) can be considered as a 'rank', whereas each memory block (or set of blocks) within an IC can be considered as a 'bank'.
