What is another word for programmable read only memories?
Pronunciation: [pɹˈə͡ʊɡɹɐməbə͡l ɹˈiːd ˈə͡ʊnli mˈɛməɹˌiz] (IPA) 
Programmable read only memories, also known as PROMs, are non-volatile memory devices that can be programmed only once. There are several synonyms for this term including one-time programmable memories (OTP), programmable ROMs, and masked ROMs. OTPs refer to PROMs that are programmed during the manufacturing process and cannot be reprogrammed thereafter. Programmable ROMs, on the other hand, are PROMs that can be programmed and reprogrammed multiple times. Masked ROMs are PROMs that have their data programmed during the manufacturing process, where the data cannot be changed afterward. All these are different types of PROMs with varying levels of programmability and reprogrammability, catering to different requirements of electronic devices.
