Résumé de section

  • This chapter introduces the fundamental concepts of memory systems used in embedded systems and computer architectures. Students will learn the role of memory in storing programs, instructions, and data, as well as its impact on system performance, power consumption, and reliability. The chapter presents the internal organization of memory, read/write operations, timing diagrams, and the main memory characteristics. Different memory technologies are also explored, including volatile and non-volatile memories, ROM, PROM, EPROM, EEPROM, Flash memory, SRAM, and DRAM. Finally, memory management challenges and optimization techniques used in modern embedded systems are introduced.

    This chapter covers the following topics:

    • Introduction to Memory Systems
