PRIMARY MEMORY: It stores programs and data which are
currently needed by the CPU. The semiconductor memory is employed as the main
memory of the computer. As the CPU employs semiconductor technology and has
very high speed, its matching memory must be very fast. Only semiconductor
devices can provide the matching speed. Thus the main memory also must employ
semiconductor technology. RAM and ROM IC’s are used as the main memory of the
computer.
