MONDAY MEMO, June 18, 2007 **************** 1. Announcements **************** 1.1: HuntAir PM Schedule, per Mark Voorhis: Since the northwest quadrant of the cleanroom will be down next week, we plan to start PM activities on the Hunt air handlers for the cleanroom. We anticipate ~1 hour of down time for each AHU. From our past history you will loose laminar air flow and the some temperature and humidity control (± 1.0F) (± 5.0%RH). Only one air handler will be down at a time. PM work should start ~8:00 AM and be completed by 4:00 PM for each day. If you have concern or issues please call Mark Voohis (43036) or Jeff Kuhn (68329).

Volunteers are needed to help staff the Discovery Park booth and engage the audience about all the exciting things happening here. We will have premiums to hand out, a stimulating display to talk about, and many opportunities for to be shared about the exciting programs and research at Discovery Park. The format will be similar to last year; we will need to staff our booth from 9am-7pm. The day will be divided into 3 shifts. More information regarding the schedule and transportation will be available in July. If you think you¹d like to participate, please mark your calendar for July 17th when the DP Engagement staff will hold a general information session from 10am-11am in MRGN 121. Another session will be held for training and more detailed information on August 9th from 10am-11am in MRGN 121. Please contact Valerie Lawless, Operations Manager, DP Engagement, (lawlessv@purdue.edu) if you would like to volunteer! ******************** 2. Seminars ******************** 2.1: Monday, June 18, 2007, 4:00pm: ³Addressing of Self-Assembled Nanoarrays,² by Prof. John E. Savage, Brown University, LWSN 3102A/B (Department of Computer Science Colloquium) ABSTRACT: Nanowire-based crossbars are proposed for use as memories and PLAs. The challenge they present is to design decoders that control many small nanowires (NWs) with a small number of large mesoscale wires (MWs). All proposed NW decoders are assembled stochastically. For example, in a randomized-contact decoder (RCD) field-effect transistors are randomly created at about half of the NW/MW junctions. In this talk, we describe our work to bind the number of MWs required to produce a correctly functioning NW decoders with high probability. We compare four methods of realizing NW decoders with emphasis on the RCD. We analyze the overhead associated with controlling a stochastically assembled decoder, namely, the information regarding which MWs control which NWs. This overhead requires more area than the MWs themselves. Finally we present several simple testing algorithms for configuring this control circuitry. This work was done jointly with Eric Rachlin.
