One Time Programmable (OTP)
Form of digital memory where the setting of each bit is locked by a fuse or antifuse. It is one type of read-only memory (ROM). The data in them are permanent and cannot be changed. OTPs are used in digital electronic devices to store permanent data, usually low level programs such as firmware or microcode. The key difference from a standard ROM is that the data is written into a ROM during manufacture, while with a OTP the data is programmed into them after manufacture. In security, it is usually used to store keys.
