HYBRID MEMORY CUBES are coming to replace the small volatile unit's giant accessory unit's a prototype is already ready .

           DDR1, DDR2 and DDR3 these are the types of Rams released in the market till now. Every Ram is same in there Shape and also same in the functionality but the thing is there is a drastic change in the frequency of the Rams. As the architecture changes the manufacturing cost of the Rams also decreases this we can see by comparing the cost of three different Rams for DDR1 cost of 512MB used to be 1000 above then as the DDR2 launched there is some decrease in the cost. Now the cost of 4GB DDR3 is just 1100 rs and also it gives the high performance.
                But now the thing is as Multi - core processing is bringing incredible changes to super computing and advanced networking systems, advances that will require a new level of memory efficiency and performance. The next upcoming Ram's have entirely new architecture that maximizes the full potential of these high-performance systems.These Rams are developed by Micron.

What is HMC?
   At the core of the HMC is a small, high-speed logic layer that sits below vertical stacks of DRAM die that are connected using through-silicon-via (TSV) interconnects. The DRAM has been designed solely to handle data, with the logic layer handling all DRAM control within the HMC. System designers have the option of using the HMC as either "near memory," mounted directly adjacent to the processors for best performance, or in a scalable module form factor as "far memory," for optimized power efficiency.

The Real Difference is in the Cube


HMC will provide a revolutionary performance shift that will enrich next-generation networking and enable exaflop-scale supercomputing:


Increased Bandwidth — A single HMC can provide more than 15x the performance of a DDR3 module.


Power Reductions — HMC is dramatically more efficient than current memory, using 70% less energy per bit than DDR3.


Smaller Physical Systems — HMC’s stacked architecture uses nearly 90% less space than today’s RDIMMs
