Unlike a byte that is always 8 bits, word size can vary from machine to machine. So, to visualize word-addressable memory, we need to know the word size beforehand. Let's say we have a 16-bit sy memory unit that has 10 address lines. How do we visualize such a memory? First, we determine the size of the memory given the number of address lines. Because there are 10 address bits, we can have 210 unique addresses, hence 1024 addresses. If we are working with means each word - not each byte - has a unique address, and we can thus store 1024 words. The memory size is 1 kiloword, or equivalently, 2kilobytes because each word is 2 bytes long: Each row is a word; each word has its own address; each word is 2 bytes long Addr Addr (Bin) Contents
