Microsoft to push further development of ‘memory cube’.
Microsoft joined the Hybrid Memory Cube Consortium earlier this month, which already includes high profile companies Samsung and IBM. Together the group is trying to advance the technology which uses stacks of DRAM memory combined together with a logic layer on top to control and optimize the memory. Traditionally memory controllers are intergrated into other parts of computers, but by combining them into the logic layer of the memory cube, higher speeds can be achieved along with lower energy consumption.
According to the Consortium, the memory cube could provide 15x the performance of DDR3 memory (which is found in most new computers today), while utilizing an amazing 70% less energy per bit than DDR3.
The group hopes to have 2 and 4 Gigabyte versions of the cube available early next year, although it’s unclear if those would simply be testing versions for developers or a finished product for mass market. They are also working on an interface for the cube to work with mobile devices, where power consumption is particularly critical. Intel is also rumoured to be considering joining the consortium.
