Decoder with multiple RAMs

[SilverKing]

Hi everyone,

I've a problem I want some help with.

"For the previous figure, write a code to make the values of the third chip all zeros, and copy the contents of the first chip to sixth and the seventh."


I want you to help me with first steps to solve this problem.

Can't help with the programming part, especially without knowing the system / CPU, but you have a 20-bit address with the top 4 bits always high and the remaining 0xF0000 thru 0xFFFFF divided evenly into 8 blocks.

Chip 1 would be 0xF0000 thru 0xF1FFF
Chip 2 would be 0xF2000 thru 0xF3FFF
...
Chip 7 would be 0xFE000 thru 0xFFFFF
