Memory is synonymous with the term primary storage

Technically, memory is not part of the CPU but is the memory that the processor (CPU) addresses on its bus.

Memory is a storage device that stores information in the form of byte.

Physical memory is organized as a sequence of:

Each byte (or word) is assigned a unique address, called a physical address. The total number of address is called an address space.

Memory consists of many cells. Each cell is a byte with its address number to access it.

Memory stores two logical type of bytes:

Memory in a Von Neumann machine does not distinguish between which bytes are data and which bytes are software instructions. (ie memory is schema less). A CPU will execute data byte if such bytes represents valid instructions.
