Over the past ten-odd years CPU performance has improved dramatically, while the speed of memory access is not risen significantly. This gave rise to the so-called problem of memory wall . The first to break this notorious wall was Micron company . In practice, this is done with the help of memory Hybrid Memory Cube (HMC). At the first stage the speed of access to the module HMC is 160 GB / s in each direction. It is so fast that one 2GB module Hybrid Memory Cube is enough to serve four new SoC FPGA Altera company. HMC Each module consists of four stacked packed in memory chips and a memory controller chip - only five layers connected by through TSVs-compounds.
Significantly on the use of HMC in personal computers, nothing is known, but SoC Altera, as it became known a few days ago, will not be the first solution that today requires a new memory. Micron company reported that at Supercomputing 13 conference, which will be held in Denver from 19 to 21 November, will be a demonstration of the prototype supercomputer using HMC. It is a platform of the Japanese company Fujitsu scale petaflops, which alludes to the use of UNIX-platform, not x86-compatible.
Based on each transmitted bit consumption when transmitting data reduced by up to 70%. Experienced 8-Gbps module HBM company SK Hynix will only show in February at the ISSCC conference in 2014 and it will be characterized by the capacity of 128 GB / s. Related Products :
