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).
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.
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.
PROM, or programmable read-only memory, stores data in a fixed form during the manufacturing process, with data retention dependent on the life expectancy of the device itself. EPROM, or erasable programmable read-only memory, is similar to PROM but can be cleared by exposure to ultraviolet light.
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)
A 16-bit address space for between 1 kibibyte (KB) and 64 KB of either programmable read-only memory (PROM, OTP), read-only memory (ROM), or flash memory, are used to store code and constants, and there is a second 16-bit address space which can be used for large applications.
Prom Night is a 1980 slasher film directed by Paul Lynch and written by William Gray. Jamie Lee Curtis and Leslie Nielsen star. The film's plot follows a group of high school seniors who are targeted at their prom by a masked killer, seeking vengeance for the accidental death of a young girl six years earlier.
