AC-DIMM

Qing Guo, Xiaochen Guo, Ravi Patel, Engin Ipek, Eby G. Friedman
2013 Proceedings of the 40th Annual International Symposium on Computer Architecture - ISCA '13  
This work proposes AC-DIMM, a flexible, high-performance associative compute engine built on a DDR3-compatible memory module.  ...  A new, bit-serial TCAM array is proposed, which enables the system to be implemented using STT-MRAM.  ...  AC-DIMM uses a novel 2T 1R STT-MRAM cell, which is 4.4× denser than a CMOS TCAM cell.  ...
