I need to build in EW the memory block P-ROM 1kb with chips 256*8. So i understand that there should be 4 chips that should be connected in consecutive way. The adresses include the A0.A6. But this chip should be connected with adress decoder with other A7.A15 to 16 bit bus. So i need to build the 4 CS inputs from decoder. But do not have algorytm. Despite I have an example to do it with 2kb*8 with 2 1kb*8. We should define base and end adress with two second variants. But how. Is it done random. For example there is such code. Base ad:11100 and other eleventh zeros. The end a:11100with other eleventh "1". How it is defined? And how to translate it to my case. Then i need to build chat with logic expression based on it that should be much easier if i would have the base and end adress.
