Reconfigurable nonvolatile programmable logic using complementary atom switch (CAS) is successfully demonstrated on a 65-nm-node test chip. Various logics are realized by synthesizing RTL codes and mapping the configurations into CAS-based programmable cell array. Each cell includes the two 4-input LUTs, 19×16 crossbar switch, and 368-b CAS. The CAS integrated over CMOS reduces the cell area by 78% compared to a conventional SRAM-based design.
