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

Moore’s Law & Transistors

1971 2,250 1974 5,000 1985 275,000 1997 7,500,000 1999 24,000,000 2000 42,000,000 More even as we

speak

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
