Memory Organization in Computer

How is memory http://www.kynix.com/Product/Cate/40.htm... in a computer? Is it 1 bit per address so in order to get the value of an integer (32 bits) it must go through 32 addresses, get all the bits of 0's and 1's? I am a bit confused since I am reading a book on computer organization and architecture but the author does a poor job explaining thoroughly. Because what is really confusing me is when book uses examples and states 16 bit word of memory for an instruction. How is a word stored in memory? For this situation would it be 16 sequential addresses?
