943<p id="mwLw">OTP (one time programmable) memory is a special type of <a rel="mw:WikiLink" href="//en.wikipedia.org/wiki/Non-volatile_memory" title="Non-volatile memory" id="mwMA">non-volatile memory</a> (NVM) that permits data to be written to memory only once. Once the memory has been programmed, it retains its value upon loss of power (i.e., is non-volatile). OTP memory is used in applications where reliable and repeatable reading of data is required. Examples include boot code, encryption keys and configuration parameters for analog, sensor or display circuitry. OTP NVM is characterized, over other types of NVM like <a rel="mw:WikiLink" href="//en.wikipedia.org/wiki/EFuse" title="EFuse" id="mwMQ">eFuse</a> or EEPROM, by offering a low power, small area footprint memory structure. As such, OTP memory finds application in products from microprocessors & display drivers to power management ICs (PMICs).</p>
