"By applying micro-threading to a DRAM core, we are continuing our tradition of innovation by designing and developing advanced technologies to improve the bandwidth between DRAMs and their associated memory controllers," said Laura Stark, vice president of Platform Solutions at Rambus. "We look forward to working with our various DRAM partners to bring this exciting new technology to the market in high-volume applications."
With the application of micro-threading to a DRAM core, separate addresses are provided to different DRAM core partitions, enabling the requesting controller to generate multiple micro-RAS and micro-CAS operations in the same time it would take to generate a single RAS or CAS command to a standard DRAM. Simultaneously accessible banks allow for concurrent retrieval of data, which are then bundled into a single transmission.
"Realistic interactive 3D applications such as games and visualization software require more complex scenes, composed of increasingly smaller textured polygons or triangles. A Rambus analysis showed that a standard GDDR SDRAM being used in a 3D application can deliver between 50 and 125 million triangles per second. If the same GDDR SDRAM were to be enhanced with micro-threading, the rate of delivered triangles would increase to between 100 and 500 million triangles per second. By enabling higher triangle rendering rates, micro-threading, as it is applied to a DRAM core, benefits the end user experience by providing richer visuals."
