Jan 13, 2025 · In the Computer System Design, Memory Hierarchy is an enhancement to organize the memory such that it can minimize the access time. The Memory Hierarchy was developed based on a program behavior known as locality of references (same data or nearby data is likely to be accessed again and again).

In computer architecture, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [1]

Memory hierarchy in computer architecture organizes storage into levels based on speed, cost, and capacity, from fast registers and cache to RAM, secondary storage (HDD/SSD), and virtual memory, optimizing performance.

These five hierarchies in a system’s memory are register, cache memory, main memory, magnetic disc, and magnetic tape. In this article, we will take a look at the Design and Characteristics of Memory Hierarchy according to the GATE Syllabus for CSE (Computer Science Engineering). Read ahead to learn more.

The gap between CPU and main memory speed is widening. Well-written programs tend to exhibit good locality. These properties complement each other well for many types of programs. They suggest an approach for organizing memory and storage systems known as a memory hierarchy.

What is Memory Hierarchy? The memory in a computer can be divided into five hierarchies based on the speed as well as use. The processor can move from one level to another based on its requirements. The five hierarchies in the memory are registers, cache, main memory, magnetic discs, and magnetic tapes.

In this chapter, we will look at the basic storage technologies—SRAM mem-ory, DRAM memory, ROM memory, and rotating and solid state disks—and describe how they are organized into hierarchies.

Computer Memory Hierarchy - We will study memory hierarchy of internal memory, cache memory, primary and secondary memory in terms of its speed, cost and capacity along with diagram.
