Abstract :
A new VIA-2 contact programming ROM architecture for quad level metal (QLM) process was developed, fabricated and tested with 100 MIPS 16 bit fixed point digital signal processor (DSP). The new ROM cell achieved nearly the same density as conventional diffusion programming ROM (only 4% bigger in area), high speed (106 MHz@VDD=1.66 V, 149 MHz@VDD=2.13 V), shorter (1/5) Turn Around Time (TAT), more immunity to process deviations, and confirmed 100 MIPS, 100 MHz operation with DSP (4.5 M Transistors) using 0.35 /spl mu/m 2.5 V/3.3 V dual gates CMOS QLM process technology.
