A programmable read-only memory (PROM) is a form of digital memory where the contents can be changed once after manufacture of the device. The data is then permanent and cannot be changed. It is one type of read-only memory (ROM).
Programmable read-only memory (PROM), or one-time programmable ROM (OTP), can be written to or programmed via a special device called a PROM programmer. Typically, this device uses high voltages to permanently destroy or create internal links (fuses or antifuses) within the chip. Consequently, a PROM can only be programmed once.
An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile.
EEPROM or E 2 PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.

Wen Tsing Chow (Chinese: 周文俊; pinyin: Zhōu Wénjùn; 1918–2001), was a Chinese-born American missile guidance scientist and a digital computer pioneer, known for the invention of programmable read-only memory or PROM.
Mask ROMs are factory programmable only and typically used for large-volume products which are not required to be updated after the memory device is manufactured. Programmable read-only memory (PROM) can be altered once after the memory device is manufactured using a PROM programmer.
IC programming is essential in providing the ability to program a range of programmable ICs used in diverse applications, from consumer electronics to industrial systems. The common types of programmable chips include: Programmable Read-Only Memory (PROM) Erasable Programmable Read-Only Memory (EPROM)
