ACM, the Association for Computing Machinery, today announced that Mark Horowitz, a professor at Stanford University, is the recipient of the ACM-IEEE CS Eckert-Mauchly Award for contributions to microprocessor memory systems.

Horowitz was the first to identify the processor to dynamic random-access memory (DRAM) interface as a key bottleneck that required architecture and circuit optimization. He pioneered high-bandwidth DRAM interfaces. In addition, modern DRAM interfaces such as SDDR and LPDDR were strongly influenced by his techniques.

In the 1990s, Horowitz also was a major contributor to the DASH and FLASH projects, which explored scalable methods for implementing cache coherency using directories rather than snooping protocols. Today almost all cache-coherent multiprocessors rely on such directory mechanisms either within or across multicores.
