PPT-Chapter 8: Main Memory Background

Von Neumann architecture Program and data is in the same memory code is data Harvard architecture Physically separate memory for code and data Program must be brought from disk into memory and placed within a process for it to be run. g a core dump Semiconductors are almost universal today Memory Cells Properties Exhibit two stable or semi stable states representing 1 and 0 Capable of being written to at least once to set state Capable of being read to sense the state Memory Cell 1 Name two differences between logical and physical addresses Answer A logical address does not refer to an actual existing address rather it refers to an abstract address in an abstract address space Con trast this with a physical address that refer Computer System Overview.

Almost the only ones of its properties that are detectable in its behavior are the organizational properties. . Cache Memory. Computer Organization and Architecture. William Stallings . 8th Edition. Memory subsystem. Typical computer system is equipped with a hierarchy of memory subsystems, some internal to the system (directly accessible by the processor) and some external (accessible by the processor via an I/O module)..
