Address and Address Space
I'm having a difficult time distinguishing address and address space in semiconductor memory such as RAM. As an example, I have a 32-bit address bus which can address 2^32 bits of memory to RAM memory. Now the RAM has memory cells, each of which are 1-bit. But these cells are grouped to form a word, which is 32-bits (since the bus length is 32 bits). Now I assume that that word is considered the "address". But if that's the case what is the "address space"?
