One Time Programmable Read-Only Memory


(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.
