Micron Hybrid Memory Cube
Micron Hybrid Memory Cube uses TSVs (Through Silicon Vias) to interconnect multiple memory die on a CMOS chip base.
* 1 HMC has ~20 times the performance of a DDR3 DIMM (8 to 72 memory parts)
* 1 HMC uses ~10% of the energy per bit compared to current DIMMs and memory channels
Future HPC Technology Building Blocks
– Optimization target: minimize price to buy more hardware
– COTS: Redirect off-the-shelf components designed for mass market
– This leveraged “Moore’s Law” density improvements
• Next Decade
– Optimization target: minimize power consumed for work performed
– Specialize and integrate: Embedded + SoCis proven design point
– This leverages “Bells Law” cost efficiency: Commodity not COTS
FPGAs were used to find opportunities to speed up a job by making things more local.
