Micron revealed Hyper Memory Cube, a new memory technology that it claims could offer a 20-fold performance increase over current DRAM memory chips. And if this isn't impressive enough, these new chips also promise to consume only about one-tenth of the power while also being smaller than traditional memory chips.
Speaking to Cnet, the company said its development breaks a longstanding problem referred to as the "memory wall" to deliver "a staggering amount of DRAM bandwidth directly to the processor."
Essentially, DRAM performance today is constrained by the capacity of the data channel that sits between the memory and the processor. This channel often becomes a choke point for data, no matter how much faster the DRAM chip itself gets, which was more recently evidenced in the industry's slow transition from DDR2 to DDR3 as desktop and notebook makers weren't really seeing a big enough improvement to warrant the move.
