With a flash memory chip kx8 512 consists of a 4 mx32 semiconductor read-only memory, try to answer: the memory address line number is how many?
Answer: for 4 mx32 memory, according to the word addressing range is 2 ^ 22, according to the byte addressing range is 2 ^ 24. Therefore, the memory address line is 24,

According to the word here addressing why is 2 ^ 22, the scope of a word is 16 bits, memory is 32 bit, the answer should not be 2 ^ 23?
