Reading and Programming Flash and EEPROM Memories

Working with non-volatile memory is an essential skill for electronics repair, firmware recovery, and embedded systems development. This course provides a structured, text-based foundation in how EEPROM and Flash memory chips store data, how they communicate with microcontrollers and programmers, and how to safely read, backup, and rewrite their contents. You will begin with fundamental hardware concepts, terminology, and memory pinouts before learning how to interface with target chips, handle hex data, and execute reliable programming workflows. What you'll learn: - Understand the architectural differences between EEPROM, SPI NOR Flash, and NAND memory - Master core serial communication protocols used by memory chips, including I2C, SPI, and Microwire - Read and dump binary firmware and configuration data using hardware programmers and software tools - Analyze, modify, and verify memory dumps using hex editors and checksum validation - Apply proper techniques for both in-circuit (ISP) and socketed out-of-circuit chip programming - Troubleshoot write protection flags, voltage mismatches, and data corruption issues The course begins with foundational memory principles and hardware definitions before walking you through practical read, edit, and write workflows through clear written guides and data examples. It is designed for electronics hobbyists, repair technicians, and embedded systems enthusiasts with no prior memory programming experience needed.
