Keynote: Rahul Sarpeshkar MIT - bioelectronics
Description of the human ear. Electrical analysis of hearing - amazing. 150mV PSU, 10 microsecond discrimination.
Outer ear = antenna
Middle ear = impedance matching network
Inner ear = wave spectrum analyzer
Inner hair cell = peak-detecting demodulator
Modeled RF Cochlea - Actual bionic ear processor 251 micro watt
Glucose battery - working in lab to produce energy

Invited Tutorial: Phase-Change Memory: Replacement or Transitional - Dr. Chung Lam
History of phase change:
Controversial David Pearson
Early patent - 1963
1968-1999 (not much progress)
Progress proceeded due to scaling in 1999. As we scale the volume of phase change area reduces, allowing a realistic amount of power consumption.
2011 - CEO samsung, "customers did not adopt memory."
Scalability - current density increases too much! Ronald Neale
Is PCM possible to replace NAND/DRAM? No
What are challenges?
-manufacturing cost
-alternative to NOR, but not competitive with NAND/DRAM once scaled.
What is PCM good for? Transformational - Storage class memory in Enterprise Systems.
