CMOS (complementary metal-oxide-semiconductor) can be defined as the small amount of memory on a computer motherboard that stores the BIOS settings. 
 
yes CMOS ( Complementary metal oxide semiconductor ) will still be able to exist in the upcoming days and in the near future 
 
the reason behind this is 
 
Besides improvements, CMOS technology is still very promising . 
 
semiconductors are so widely used in computer systems that to ignore them is simply impossible
 even with day by day improvement in the technologies i don't think that importance of CMOS will reduce.
