Objectives
• To discuss new possible memory candidates
– Nanowire Phase-change memory
– Magnetic Race-Track Memory
– Spin-torque Transfer Memory
• To develop quantitative estimates of performance for
the various types of memories
– We need to discuss and agree on the methodology we
use and the numbers we obtained
– It is highly desirable to document the results, ideally as a
journal publication

New Memory Candidates
• Nanowire Phase-change memory
Does is belong to PIDS or to ERD?
PC-RAM has been transferred from ERD to PIDS in 2003
• Magnetic Domain Wall Motion memory
– Magnetic race-track memory
• Stuart Parkin, “Magnetic race-track – a novel storage
class spintronic memory”, Intern J. Mod. Physics B 22
(2008) 117
• Spin torque transfer MRAM

Evaluation Criteria Outline
Cautions
– Do not over-constrain the problem based on present
day understandings
– Sufficiently advanced technologies will create their
own applications. New technologies cannot
necessarily be justified by current day applications.

Work in Progress --- Not for
“Minimum Requirement” Criteria
• The ‘minimum requirements’ criteria for a new
technology to be considered as a candidate for
ERD chapter is sufficient research activity, e.g.
– the technology is explored by several research
groups, or
– There is an extensive research activity of one
group
– There are at least 2 publications in peer-reviewed
journals
8 ERD WG 4/2/08 Koenigswinter FxF Meeting
Work in Progress --- Not for
General ‘Loose’ Criteria
• Potential for scaling
– Roadmap Driver
• On-chip integrated solutions
– Potential for embedded applications
• Outstanding research issues exist
– Guidelines for the research community and
government funding agencies
• Not in production
– Innovation phase

Meeting Outcome
• The end goal is to update and significantly
improve the ERD Chapter, and, in particular, the
Emerging Research Memory Section, for the
2009 Road Map.
