ITE221 Module 3: The Grand Illusion: A Guide to the Memory Hierarchy

This text explores the memory hierarchy, explaining how computers use a tiered system to balance speed, capacity, and cost. It details the spectrum of storage technologies, ranging from blazing-fast CPU caches to massive but slow hard drives, while highlighting the clever engineering required to make memory feel instantaneous. The source specifically examines non-volatile RAM types, the physical mechanics of DRAM, and the "illusion" of virtual memory that allows systems to run large applications. Furthermore, it addresses common performance bottlenecks like memory leaks and thrashing, offering practical strategies for optimizing code through better cache utilization. Ultimately, the material serves as a comprehensive guide for understanding how hardware and software collaborate to manage data persistence and retrieval. How does the memory hierarchy balance speed, capacity, and cost through architectural layers? Why are temporal and spatial locality essential for effective cache and system performance? How does virtual memory create the illusion of infinite space using address translation?
