Von-Neumann Bottle Neck
Memory is 1 Dimensional Must right code to model data that is
often 2 dimensional Keep floating point and integers
separate index registers, indirect addressing, and
virtual memory

Extending Moore’s Law
Nanotechnology– Nan 1 * 10 E-9– Greek word for “Midget”– Placing atoms where we want them
• Atomic Force Microscopy• Scanning Probe Microscope

Building Tomorrows Chips“one atom at a time”
E-beam Etched Microchips on the nano scale•100 NM wide isolated lines•150 NM wide nested lines

Size Examples
100 NM = 0.0000001 meter 10 UM = 0.00001 meter
Current Etched Size = 13 Microns E-beam lithography can yield 5NM
