ABSTRACT
The memory system serves as the repository of information (data) in a computer system. The processor (also called the central processing unit, or CPU) accesses (reads or loads) data from the memory system, performs computations on them, and stores (writes) them back to memory. The memory system is a collection of storage locations. Each storage location, or memory word, has a numerical address. A collection of storage locations form an address space. Figure 18.1 shows the essentials of how a processor is connected to a memory system via address, data, and control lines.
