DDR5 Memory Specification Released
>Combined with die stacking, which allows for up to 8 dies to be stacked as a single chip, then a 40 element LRDIMM can reach an effective memory capacity of 2TB. Or for the more humble unbuffered DIMM, this would mean we’ll eventually see DIMM capacities reach 128GB for your typical dual rank configuration.<p>So on 8 Channel 16 DIMM per socket you could fit a theoretical 32<i>TB</i> of memory. This is insane amount of memory and great for In-Memory Database. ( How is Intel Optane going to compete? )<p>This makes me wonder, what makes DRAM so expensive? It is still hovering at a median price or around $3/GB compared to NAND which is less than $0.1/GB.
