morphic) architectures (Paul Franzon, Tetsua Asai and the Architecture Working Group will explore and develop this approach.
Franzon and Asai
3. Should Storage Class Memory drive a new architecture discussion in the Architecture Section? Explore a definition of SCM
Zhirnov and Schechtman
4. Explore fitting the SET for ADC application in the MtM Section. The SET is still in active research at NTT in Japan.
Brillouet
5. Develop a table of Devices mapped onto materiel and their critical property required to demonstrate the key attribute of the device.
BourianoffGarner and Zhirnov
6. Rename the FeFET to include the Fe-barrier device. Zhirnov7. Send ITRS URL Link to obtain the PPT files of this meeting Hutchby
8. Change “Nanobridge Cantilever” to just “Nanobridge” Zhirnov9. Talk to Jeff Welser regarding which NRI devices meet our
criteria to include them in the ERD Chapter.Bourianoff
10 Consider including items related to on-chip technology integration or “Technology Fusion”
Brillouet
11. Change Architecture part of Taxonomy Chart. Hutchby12, Make the NRI benchmarking methodology available to ERD Welser
13, Prepare a standalone section on benchmarking new devices using new device parameters

Feedback on 2009 ERD Chapter Overall Comments
Excellent overall readability and balance as a summary Appropriate level of detail Scope
Define the terrain covered by performance gains Define “ultimately scaled CMOS” Clarify “new information processing paradigm” Clarify “bulk CMOS”
Difficult Challenges Clarify the term “bridge a knowledge gap” Italicize “This development would provide a significant increase in information …” Give an example of a new application that can be better performed by a new device than
by CMOS. Taxonomy – How useful is this to the reader? Critical Assessment
Some editorial comments Define “functional” Is the term “access resistance” sufficiently general? Comment on “compared to the existing memory technology” Should it say “compared to
existing memory technology scaled to its limit:”? How can we obtain more votes in the Critical Review? Include the OPA score in the left column of ERD 14 and 15.
Work in Progress --- Not for Publication14 ERD WG 7/10/2011 San Francisco, CA. FxF Meeting
Feedback on 2007 ERD Chapter Overall Comments (Held over)
Mission of ERD is not clear cut to universities – clearly state the mission in the introduction.
Need more detailed discussion of key messages and issues between ERD and ERM
Is a Technology Entry being limited by Fundamental Limits or a technologically limited research gap?
ERD needs to maintain a dialog with the Systems Drivers Chapter Should ERD continue to include a failing Technology Entry?
Work in Progress --- Not for Publication15 ERD WG 7/10/2011 San Francisco, CA. FxF Meeting
Feedback on 2009 ERD ChapterEmerging Research Memory Devices
♦ Transfers Expand the scope by including a new section on the “Select Device”, either a
diode or transistor Expand the scope by including Storage Class Memorysuch as Magnetic
Packet Memory ( Racetrack) Move Nanowire Phase Change Memory to the Memory Transition Table and
recommend its transition to PIDS as a variant of PCM. For the time being, keep the Electronics Effects Memory intact as a category
for further discussion, with the exception of moving Fe Polarization Memory to the FeFET category and devising a new name to distinguish this from the Fe Capacitor Memory
Add a row in the Memory Table to include an indication of a particular memory suitability for SCM
♦ Other comments Include optical memory for More-than-Moore? Need to define (or make a table) a role ( necessary condition) of memory
element as an interconnection. Examples ;o For configurable logic using such as CMOLo For Inference Architecture such as Bayesian inference networks
Work in Progress --- Not for Publication16 ERD WG 7/10/2011 San Francisco, CA. FxF Meeting
Feedback on 2009 ERD ChapterEmerging Research Logic Devices (1/3)
♦ Transfers III-V Alternate Channel Materials to PIDS/FEP and Low Dimensional Materials to PIDS/FEP (keep GNR & CNT FETs) Move Molecular Devices to the Transition Table. Include Band-to-Band Tunneling Device category in Table 1. Move RTD out of Table 2 to Transition Table
♦ Other comments (decisions) Keep the 3 Logic Tables used in 2009 and change “Channel” to “Device”
in the first table. Keep open for more discussion the disposition of vertical MOSFETs –
Decide in Dec. Meeting Put the Tunnel Transistor in the Transition Table for Logic Add a new Section on More-than-Moore focused on Wireless Devices. Move the SET to the new More than Moore Section Move the Negative Capacitive Devices to the Logic Transition Table
Work in Progress --- Not for Publication17 ERD WG 7/10/2011 San Francisco, CA. FxF Meeting
Feedback on 2009 ERD ChapterEmerging Research Logic Devices (2/3)
♦ Other comments (decisions) Include the “Mott FET’ in the Logic Tables. (Call it Electronic Phase Change?) Mention “Excitonic Device” in the Logic Text – put in the Logic Transition
Table? Under Collective Spin Devices include: Spin Wave Device and All Spin Logic The IRC approved the ERD and ERM to publish the results of the Barza
Memory Workshop, but make clear that this is not a selection of a technology Transfer unconventional FET s, Tri-Gate, FinFET, GAA FETs, to PIDS/FEP
♦ Other comments (under discussion) In the Logic Transition Table, the IN/OUT entries for Ge FET, Spin MOSFET,
Collective Spin Devices, Pseudomorphic, and Nanomagnetic Devices should be move into the Comment column to the right. Entries in the IN/OUT column might better be technical in nature.
Work in Progress --- Not for Publication18 ERD WG 7/10/2011 San Francisco, CA. FxF Meeting
Feedback on 2009 ERD ChapterEmerging Research Logic Devices (3/3)
♦ Other comments (under discussion) Introduction of energy efficiency criteria? Important Role of other functionality than digital of beyond CMOS: image
processing, analog, RF, etc. Convergence of beyond CMOS and More than Moore technology
entries? MEMS/NEMS already in chapter. More interaction with emerging architectures needed.

“Guiding Principles” Computational state variable(s) other than solely electron charge. These
include spin, phase, multipole orientation, mechanical position, polarity, orbital symmetry, magnetic flux quanta, molecular configuration and other quantum states.
Non-thermal equilibrium systems to reduce the perturbations of the stored information energy by thermal interactions with the environment (e.g., systems that perform all processing functions in a time short compared to the system’s energy relaxation time to improve thermal noise immunity).
Nanoscale thermal management. This might be accomplished by manipulating lattice phonons for constructive energy transport and heat removal.
Novel information transfer mechanisms. These mechanisms would provide the interconnect function between communicating information processing elements, and input/output.
Alternative Architectures. In this case, architecture is the functional arrangement on a single chip of interconnected devices that includes embedded computational components. These architectures should utilize, for special purposes, novel devices other than CMOS to perform unique functions.
Sub-lithographic manufacturing process (e.g., directed self-assembly of complex structures composed of nanoscale building blocks) The approaches should address essential non-regular, hierarchically organized structures, be tied to specific device ideas, and be consistent with high volume manufacturing processes.
