Ok nice for you anwser everybody! Some anwser bring me to learn nore about cmos technology..and i realised learn that memory cells today were made from cmos gates because of the power consumption. So i found on the web cmos sram chip that cost only a couple bucks and the greastest thing is that most of them are ttl compatible. That is really nice! Many chip today are made of cmos and ttl. Because ttl is faster and cheaper ill probably use them for logic..
Now that i will use cmos sram..ill save power consumption and save money and space and i'll will have more memory 
There are few ttl sram ttl chip on the market and they get a 4 bit scale data bus.
If someine is interest in a cpu project tell me i would really love to create a community to share design and idea with people interest in it!
(And sorry for my english i am from quebec i my native language is french.
