The 2022 ACM Eckert-Mauchly Award has been awarded to Mark Horowitz who pioneered the DRAM Interface and whose insights at the intersection of architecture and circuits have had a profound influence.

Eckert Mauchly banner Administered jointly by ACM and IEEE Computer Society, this  annual award of $5,000 recognizes contributions to computer and digital systems architecture and combined hardware-software design. It is named after John Presper Eckert and John William Mauchly, who collaborated on the design and construction of one of the very first computers - ENIAC (Electronic Numerical Integrator and Computer) completed in 1947. You can discover their story in Eckert & Mauchly and ENIAC.

The citation for the 2022  Eckert-Mauchly Award reads:

“For contributions to  microprocessor memory systems"

and its recipient is Mark Horowitz who is the Yahoo! Founders Professor in the School of Engineering and Professor of Computer Science at Stanford University. His current interests include applying electrical engineering and computer science analysis methods to problems in neuro and molecular biology as well as creating new agile design methodologies for analog and digital VLSI circuits. Horowitz also co-founded the company Rambus, Inc., which designs high-bandwidth memory interface technology. 

Mark Horowitz

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 was also 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. 

Horowitz demonstrated the growing importance of wire delay in systems with large memories through his landmark paper, “The Future of Wires” in 2001. He also pioneered work in Smart Memories, an early work customizing memory as well as processors; many of today’s domain-specific architectures build on this concept.

Horowitz was formally recognized at the ACM/IEEE International Symposium on Computer Architecture (ISCA), which was held June 18-22, 2022 microprocessor memory systems.
