Definition

Noun: 1. (Computer Science) A type of non-volatile memory chip: A specific category of read-only memory (ROM) that can have its stored data erased, typically by exposure to ultraviolet light, and subsequently reprogrammed with new data. This allows for updates and corrections after manufacturing.

Usage

• The term is a technical compound noun, most commonly used in its abbreviated form (EPROM). It is used to describe a specific hardware component in computing and electronics.
• It functions as a countable noun (e.g., , ).

Examples

• Noun:
  • The firmware for the early device was stored on an erasable programmable read-only memory chip.
  • To update the code, the engineer removed the erasable programmable read-only memory from the circuit board and placed it under a UV eraser.
  • Development was easier using erasable programmable read-only memory because we could reprogram it multiple times.

Advanced Usage

• The term is often used historically or in technical documentation to distinguish this technology from other types of memory like Mask ROM, PROM, or the later EEPROM (Electrically Erasable Programmable Read-Only Memory).
• The process is described as "blowing" or "burning" an EPROM when programming it, and "erasing" or "UV-erasing" it.

Variants and Related Words

• EPROM (noun): The standard and overwhelmingly more common acronym for "erasable programmable read-only memory."
  • The BIOS was stored on an EPROM.
• EEPROM (noun): Electrically Erasable Programmable Read-Only Memory; a later, more advanced type that can be erased and reprogrammed electrically without removal from the circuit.
• PROM (noun): Programmable Read-Only Memory; a one-time programmable memory chip.
• Flash memory (noun): A later, block-based form of EEPROM that is now the dominant technology for non-volatile, rewritable storage.

Synonyms

• Non-volatile memory (noun, broader category): A general term for memory that retains data without power. EPROM is a specific type of non-volatile memory.
• Firmware storage (noun phrase, functional description): Describes one of its primary uses.

Related Phrases

• UV-erasable PROM (noun phrase): An alternative descriptive name that emphasizes the erasure method.
• OTP EPROM (noun phrase): One-Time Programmable EPROM; an EPROM used without the erasure window, making it function like a PROM.
