News First Samsung A-Die Memory Sighting Points to Low-Priced DDR4

Dual rank? That means additional latency in memory timings.

That's surprising. Isn't that reserved for mem sticks with lots of chips slapped on them? I thought with the node shrink higher capacity would be put on a single chip and not multiple chips. It would keep the die small, and raise the yield rate, but at the cost of access times.

Or is my understanding incorrect? (All the memory timing specs are still somewhat a mystery to me.)
