Abstract :
Seven FinFET devices optimized for 7nm technology along with three SRAM cells were evaluated and compared. The high_l device has the lowest OFF current and the highest ON/OFF current ratio. Moreover, 8T SRAM cell achieves the highest SNM which guarantees its robust operation. Hence, 8T SRAM cell using high_l devices is suggested as the choice of memory cell for the discussed 7nm FinFET process.
