• (^) 65nm Logic Technology

Intel recently disclosed details of its 65 nm

generation logic technology which includes

numerous features to improve performance and

reduce power. This technology is being

demonstrated on fully functional 70 Mbit SRAM

chips with over 1/2 billion transistors. Once

again proving that Moore’s Law is alive and well,

Intel’s 65 nm technology is on track for delivery

in 2005.
