noun
UV-EPROM; ultraviolet erasable programmable read-only memory
A type of non-volatile memory chip that can be erased by exposure to ultraviolet light and then reprogrammed. Used in older embedded systems and microcontroller development.
このマイコンには紫外線消去型ＥＰＲＯＭが使われている。
This microcontroller uses a UV-EPROM.
紫外線消去型ＥＰＲＯＭは、窓付きのパッケージが特徴です。
UV-EPROMs are characterized by their windowed package.
EPROM is the broader category; 紫外線消去型ＥＰＲＯＭ specifically refers to the UV-erasable variant, as opposed to one-time programmable (OTP) or electrically erasable (EEPROM) types.
EEPROM is electrically erasable and does not require UV light; it can be rewritten in-circuit, while UV-EPROM needs physical removal and UV exposure.
Compound of 紫外線 (ultraviolet rays), 消去 (erasure), 型 (type), and the English acronym EPROM (Erasable Programmable Read-Only Memory).
