Capacitor-less memory might show up on your next AMD processor

EETimes is reporting that AMD has just entered an agreement with memory startup Innovative Silicon to license the company's capacitor-less SRAM alternative.  Innovative Silicon's technology, Z-RAM, uses zero capacitors in its memory design.  Not only does this reduce the cost of the memory, but density of such memory is also much greater.

AMD uses traditional SRAM for onboard CPU cache in its desktop and server processors.  Technologies like Z-RAM could give AMD the opportunity to significantly increase the amount of cache on its CPUs, or use the newly aquired die real estate for something else.  An interesting side benefit of Z-RAM is that it currently can only be produced on silicon-on-insulator (SOI) wafers.  AMD made the move to SOI process over a year ago. 

Innovative Silicon has already demonstrated Z-RAM on the sub-100nm scale. Its corporate roadmap expects to see sub 40nm nodes by 2012.
