<p>address pins, which specifies which word in the chip is to be accessed.  If the memory address consists of M bits, the number of addresses on the chip is 2<sup>M</sup>, each containing an N bit word.   Consequently, the amount of data stored in each chip is N2<sup>M</sup> bits.  The memory storage capacity for M number of <a href="page.php?w=address_line">address line</a>s is given by 2<sup>M</sup>, which is usually in power of two: 2, 4, 8, 16, 32, 64, 128, 256 and 512  and measured in <a href="page.php?w=kilobit">kilobit</a>s, <a href="page.php?w=megabit">megabit</a>s,</p><p>
