One Time Programmable Read-Only Memory
(storage)(OTPROM, EPROM OTP) A kind of storage device like an
EPROM but with no quartz glass window in the package for
erasing the contents. This reduces the packaging cost but
means the device cannot be erased with UV and so can only be
written once. Erasure is possible, but expensive, with
X-rays.
