Abstract
A triple-poly process forms a static random access memory (SRAM) which has a compact four-transistor SRAM cell layout. The cell layout divides structures among the three layers of polysilicon to reduce the area required for each cell. Additionally, a contact between a pull-up resistor formed in an upper polysilicon layer forms a “strapping” via which cross-couples a gate region and a drain region underlying the strapping via. Pull-up resistors extend across boundaries of cell areas to increase the length and resistance of the pull-up resistors.
