Apr 30, 2020 · EEPROM is a type of non-volatile primary memory and modified version of EPROM (Erasable Programmable Read-Only Memory) which uses electrical signals to erase and program the contents rather than UV signals which was used previously in EPROM. Compare SRAM vs DRAM, NOR vs NAND. It is used in computers, usually integrated in microcontrollers such as smart cards and remote May 11, 2022 · Developed in the late 1970s and early 1980s by researchers at Hughes Aircraft and Intel, EEPROM was used as a replacement for EPROM (erasable programmable read-only memory) and PROM (programmable read-only memory) memory. This guide explains Flash, RAM, and EEPROM, their differences, usage, and real-world applications in microcontrollers. EEPROM allows for byte-level read and write operations, making it suitable for applications requiring frequent small updates. ROM (Mask Programmable ROM—also called “MROMs”) EPROM (UV Erasable Programmable ROM) OTP (One Time Programmable EPROM) EEPROM (Electrically Erasable and Programmable ROM) Flash Memory - This device is covered in Section 10. Upper insulator: ONO Lower insulator: tunnel oxide STMicro M24C02 I²C serial type EEPROM Atmel AT93C46A die AT90USB162 MCU integrates 512 Byte EEPROM EEPROM or E2PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is an array of floating-gate transistors individually programmed by an electronic Jul 12, 2025 · EPROM contributed significantly to the advancement of computer hardware by striking a balance between adaptability and durability. Understanding EPROM Memory Types EPROM (Erasable Programmable Read Only Memory) is a type of memory that can be erased and reused by exposing it to ultraviolet light. Digi-Key - Memory Technology in Electronics — Digi-Key provides articles and guides focusing on memory technologies such as EPROM and EEPROM, with discussions on their architecture, advantages, and limitations. Mar 17, 2026 · EPROM served as an important stepping stone in memory technology, bridging the gap between mask ROM and electrically erasable memories. An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. EEPROM chips have a life span of 10,000 to 1,00,000 write cycles, comparatively more than EPROM chips. Overview of EEPROM Architecture and Components EEPROM architecture typically consists of a memory cell array, row and column decoders, sense amplifiers, and control logic. It has becoming a more popular option for firmware storage in a wider range of devices due to its long term data preservation and ability to be programmed again. Before the era of EEPROM and flash memory, EPROM was used in microcontrollers. Jun 23, 2025 · EEPROM Architecture and Operation In this section, we will delve into the architecture and operation of EEPROM, including its components, data storage, and retrieval mechanisms. Prior to the use of EEPROM, EPROM technology was widely used. Jul 23, 2025 · Several types of ROM like Mask ROM, PROM, EPROM, and EEPROM performs several purposes and offers different ways to store and sometimes update data. Oct 21, 2022 · EPROM (erasable programmable read-only memory) is memory that does not lose its data when the power supply is cut off. A cross section of legacy EPROM structure. Types of Electrically Erasable Programmable Read Only Memory There are two types of EEPROM memory chips available – Serial EEPROM Serial EEPROMs utilize a serial interface for data communication. Learn how memory works in embedded systems. It differs from other memory types like ROM, PROM, and EEPROM in its ability to be reprogrammed and erased, making it useful for applications such as microcontrollers and debugging. We would like to show you a description here but the site won’t allow us. Complete guide to memory IC types: RAM, ROM, Flash, EEPROM explained. Mask ROM is ideal for fixed, unchanging data, while PROM allows customization for specific needs. Jul 31, 2022 · An in-depth exploration of various types of computer memories, including their architecture, components, and access methods. The data can be erased and the chip reprogrammed by shining an intense ultraviolet (UV) light through a window designed into the memory chip. Reprogrammed it is limited. EEPROM and Flash memory both offer non-volatile storage, but they differ in their architecture and use cases. Jul 23, 2025 · EPROM (Erasable programmable read-only memory): EPROM also called EROM, is a type of PROM but it can be reprogrammed. In this article, we will explore the definition, history, and importance of EPROM, as well as its architecture and applications. While largely superseded by EEPROM and flash memory, EPROM's principles laid the foundation for modern non-volatile memory technologies used in embedded systems today. Short Note on ROM: Introduction to Semiconductor Memories, Different Types of ROM like PROM (programmable read-only memory), EPROM, EEPROM, and Masked ROM.
