Jelight Co.Inc.established 1978, recognized producer quality ultraviolet light sources related equipment. expertise gained throughout years assisted designing wafer EPROM erasers with superior performance productivity. High Intensity Lamp Design Operating intensity least greater than competitive systems increased throughput. Excellent uniformity insures fast complete erasure. EPROMs Work?
basic memory element developed Frohman-Bentchkowsky Intel Corporation known (FAMOS) transistor. essentially silicon gate field effect transistor which connection made gate. gate fact electrically "floating" insulating layer silicon dioxide. devices have been fabricated structures: p-channel n-channel. p-channel devices were first EPROMs available commercially, many devices using nchannel technology. N-channel devices have advantage being able function with single power supply. application sufficiently large potential difference between source drain, charge injected into "floating" gate which induces charge substrate. sourceto-drain impedance changes "p-channel" "n-channel" created, depending upon type substrate. presence absence conduction principle data storage. Application short wave (254 ultraviolet radiation causes gate charge leak away restores device original unprogrammed state. EPROM manufacturers provide "nominal erasing energies" their devices; amount energy required erase chip's memory. Erasing time calculated using following formula:
Most EPROMs have nominal erasing energy Some chips, however, require little much complete erasure.
