Memory Question

After a row in a memory chip is activated, it cannot be closed and another row in the same bank be opened until a minimum amount of time has elapsed. This is why having more memory banks can help to improve memory performance, provided it does not slow down other areas of the memory.

However, it is also known that data travels faster inside a memory chip than on the physical data bus and pin connections. Perhaps its safe to say that having fewer high density chips is better in this regard.


Wondering if you guys can shed some more light on this subject:

Which memory module configuration offers better performance in theory:

DDR400 PC3200:
1GB module 128Mx64, built using: 64Mx8, 16 chips, 2 memory banks
1GB module 128Mx64, built using: 128Mx8, 8 chips, 1 memory banks.

In theory everything else being equal the 2 bank memory stick will perform better, in pratice most 2 bank modules in the 1GB category (pretty much all of the commonly produced ones at this point) have worse timings and won't support lower command rates than a similary priced 1 bank dimm.
