How is the word size of RAM and its capacity related to number of addressing bits? A RAM has a capacity of 1M words having the word size of 32 bits and supports byte addressing.

how many address lines and how many data lines are needed for this RAM ? that question.

If we want the RAM to be word addressible, then a processor with n address bits, can address 2^n words in the RAM.
RAM has capacity 1 Mega words. = 1024 words = 2^10 words.
Each word size = 32 bits or 4 bytes.
1) data input lines/output lines:
32 as many as the number of bits in a word
2) address lines needed:
since there are 2^10 words total, we need 10 address lines.
