Rambus says DRAM micro-threading will make graphics fly

MEMORY IP company Rambus claimed it has develped technology which will allow microthreading of DRAM cores which can deliver up to four times performance compared to the current approach.
The technique allows DRAM to provide more data bandwidth by allowing smaller pieces of data to be transferred to and from the chips, which also has the side effect of keeping power consumption to a minimum.
Separate addresses are provided to different memory core partitions while simultaneously accessible banks can give concurrent retrieval of data in one single transmission, Rambus claimed.
That means that, for example, that while a standard GDDR SDRAM used by a 3D app can deliver between 50 and 125 million triangles a section, multithreading such a memory can deliver between 100 and 500 triangles a second.
There's little cost to adding micro-threading, claimed Rambus. DRAM controller need to be optimised for the new technology. Rambus has already applied for a patent and, not much surprise this, is ready to license it to you.
