OTP ROM

OTP ROM, or One-Time Programmable Read-Only Memory, is a type of non-volatile computer memory that is programmed once and cannot be reprogrammed. OTP ROM is used to store data that needs to be permanently stored and cannot be changed or updated in the future.

OTP ROM is created using a process similar to that used to manufacture Mask ROM. However, instead of programming the memory during the manufacturing process, OTP ROM is programmed after the manufacturing process, but before it is delivered to the customer. This allows the customer to program the memory with the data that they need to store permanently.

OTP ROM is commonly used in devices such as microcontrollers, smart cards, and other electronic devices that require permanent storage of data. It is ideal for storing critical data, such as system settings, encryption keys, and other sensitive information that needs to be permanently stored and cannot be changed or updated in the future.
