Abstract

Programmable-logic array that utilizes complementary atom switch (CAS) is fabricated by using 65-nm node CMOS process. A 16-bit ALU is implemented and operated on a 24x24 programmable-logic array including 645-kbit CAS for routing switch and configuration memory. Comparing the conventional cell design using CMOS routing multiplexer (MUX), the proposed programmable-logic array exhibits 60% active power saving and 3 times faster operation.
