Hybrid Memory Cube.. Heard of it? Probably not, but in the not too distant future it will potentially bring a host of hidden advantages to modern computing.
So what is it? Read on to find out!
Hybrid Memory Cube is a new DRAM memory design architecture, set to replace the existing DDR style RAM that has served us loyally over the last 15 or more years. It is a fresh look at how data is stored and accessed, bringing a layered approach to the structure of the modules. The specification has been written by the Hybrid Memory Cube Consortium, founded by Samsung and Micron and has just reached version 1.0. Whereas technologies such as DDR4/5 are the evolutionary step forward from the current standard of DD3, HMC has been designed and built from the ground up. The result is a more power efficient design, which is quoted to use 70% less energy than DDR3 RAM, as well as taking up almost 90% less space than the current designs.
Despite the the power and size advantages, there is certainly no trade-off in terms of speed. The theoretical max throughput of a single (eight-link) cube is 320GB/s! When you compare that to the typical 11GB/s that DDR3 gives us, the difference is awesome. As with a lot of these new technologies, they will likely begin their lives on server architecture and high performance systems. The advantages for both are clear, providing the rest of the hardware can keep up!
The likelihood is that given time and adoption, the cost will go down and the usage will become more widespread, reaching our home and mobile devices in the future. If it lives up to the promises, we can safely see a path for memory architecture to take us down in the future!
