Click to expand... If we have only the information stated in my first post, and the number of data lines is not known, can we tell the word size? In my opinion, it's not possible, right? Thanks.

To compute for Address bus size 2^n = 4GB Take logarithm on both sides you get 32 address bus lines. If it happens that each memory location has 1 byte then you get 4GB
