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 (Electrically Erasable Programmable ROM) offer users excellent capabilities and per-formance. Only one external power supply is required since the high voltage for program/erase is internally generated.

EEPROM or E2PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.

Mar 20, 2025 · Explore examples of ROM, including Mask ROM, EEPROM, and Flash ROM, with examples and uses. Learn how ROM is essential for computing and embedded systems.

EEPROM is a type of non-volatile ROM that enables individual bytes of data to be erased and reprogrammed. That is why EEPROM chips are known as byte erasable chips. EEPROM is usually used to store small amounts of data in computing and other electronic devices.

The program/erase cycle refers to the number of times that a chip can be erased and reprogrammed before it becomes unusable. At this time, the program/erase cycle is 100,000 for Flash and EEPROM, 1000 for UV-EPROM, and infinite for RAM and disks.

Definition: EPROM (pronounced ee-prom ) stands for Erasable Programmable Read-Only Memory. EPROM is a type of ROM chip that can retain the data even if there is no power supply.

Erasable Programmable Read-Only Memory chips consist of a grid of memory cells, each capable of storing a single bit of data. Each cell is composed of a floating-gate transistor that can be electrically programmed to store a charge, representing either a “0” or a “1.”

Mar 6, 2025 · These chips, called electrically erasable programmable ROM (EEPROM) chips, can be cleared and reprogrammed from inside a computer. Additionally, EEPROM chips allow computer engineers to erase and reprogram a small part of a chip rather than erasing and reprogramming its entire contents.

Apr 25, 2022 · The Erasable Programmable Read Only Memory is a memory chip that does not lose data even when the power is switched off. This is a non-volatile memory type i.e. it retains data even when the power is switched off. Each EPROM is individually programmed by an electronic device.
