| has gloss | (noun) (computer science) a read-only memory chip that can be erased by ultraviolet light and programmed again with new data EPROM, erasable programmable read-only memory |
| has gloss | eng: An EPROM, or erasable programmable read only memory, is a type of memory chip that retains its data when its power supply is switched off. In other words, it is non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased only by exposing it to strong ultraviolet light. That UV light usually has a wavelength of 253.7nm (for optimum erasure time) and belongs to the UVC range of UV light. EPROMs are easily recognizable by the transparent fused quartz window in the top of the package, through which the silicon chip is visible, and which permits exposure to UV light during erasing. |

| has gloss | ces: EPROM je angl. zkratka pro Erasable Programmable Read-Only Memory. Jedná se o semipermanentní typ paměti typu ROM-RAM, jejíž obsah je mazatelný ultrafialovým zářením (UV). Před novým naprogramováním je nutné paměť smazat. K programování se používá většinou několikanásobně vyšší napětí než ke čtení (typ. 12 V nebo 25 V proti 5 V napájecího napětí). |

Tyhjennykseen sopii parhaiten allonpituudeltaan 235nm UV-valo, jolloin piiri tyhjenee noin puolessa tunnissa. EPROM:in tunnistaa helposti piirin päällä olevasta kvartsilasi-ikkunasta joka siinä on oltava tyhjentämistä varten. Ikkunan päälle liimataan usein foliotarra vahinkotyhjentymisen estämiseksi.

| has gloss | ita: La EPROM, acronimo di Erasable Programmable Read Only Memory, è una memoria di sola lettura cancellabile tramite raggi ultravioletti. Si tratta di unevoluzione della PROM che, una volta programmata, non può più essere in generale modificata. La EPROM invece può essere totalmente cancellata (per un numero limitato ma consistente di volte) e riprogrammata a piacimento. La sua invenzione, nel 1971, è dovuta ad un ingegnere israeliano, Dov Frohman, fuoriuscito dalla Fairchild Semiconductor per unirsi a Moore, Noyce e Grove, fondatori della società Intel, fuoriusciti da Fairchild lanno prima. |

| has gloss | por: Uma EPROM, ou erasable programmable read-only memory, é um tipo de chip de memória de computador que mantém seus dados quando a energia é desligada. Em outras palavras, é não-volátil. Uma EPROM é programada por um dispositivo eletrônico que dá voltagens maiores do que os usados normalmente em circuitos elétricos. Uma vez programado, uma EPROM pode ser apagada apenas por exposição a uma forte luz ultravioleta. EPROMs são facilmente reconhecíveis pela janela transparente no topo do pacote, pela qual o chip de silício pode ser visto, e que admite luz ultravioleta durante o apagamento. Esta janela transparente é feita de cristal para permitir a passagem da luz ultravioleta, pois o vidro comum bloqueia grande parte do UV. O corpo de uma EPROM é feito em Cerâmica, pois o Epoxy comumente usado em outros chips não seria apropriado para garantir a fixação da janela de cristal. O processo de apagamento dura de 10 a 30 minutos. |

Diğer bir deyişle bu veriler kalıcıdır. Bu, normalde elektronik devrelerde kullanılandan daha yüksek voltaj sağlayan bir elektronik cihaz tarafından her biri ayrı ayrı programlanmış olan bir kayan geçit transistörleri “floating gate transistors” dizilimidir. Bir kere programlandıktan sonra EPROM, sadece kuvvetli mor ötesi ışığa maruz kaldığında silinebilir. Söz konusu mor ötesi ışık (en uygun silme süresi elde edilmesi için) genellikle 235nm dalga boyuna sahiptir ve UV ışığın UVC erimindedir. EPROM’lar paketlemelerinin tepesinde bulunan saydam kuartz pencereleri ile kolayca ayırt edilebilir. Bu saydam pencereden silikon çip görülebilir, pencere aynı zamanda silme işlemi sırasında UV ışığın içeri girmesini sağlar. |
