CMOL Digital Logic Circuits

Summary

We have shown that hybrid CMOS/nanoelectronic (“CMOL”) technology may be used for the effective implementation of reconfigurable logic circuits. In particular, detailed calculations have shown [1-3] that cell-FPGA-like CMOL circuits may have the area-delay product at least two orders of magnitude lower than that of similar CMOS FPGA circuits dissipating the same power per unit area and fabricated with the same CMOS process. This advantage is almost completely due to higher density of CMOL circuits, while their speed is close to that of their CMOS counterparts. On the other hand, in some custom circuits, for example those for parallel processing of images from focal plane arrays [4, 5], the density advantage of CMOL circuits may be lower, but operation speed much faster than that in CMOS, due to dramatically shorter interconnects.
