Why do you keep repeating your errors?
ROM is an acronym for "Read-Only Memory"
Are PROM's Read-Only Memory? Yes.
Are EPROM's Read-Only Memory? Yes.
HINT: The ROM in PROM and EPROM means that same thing as ROM.
What you are attempting (and failing) to argue is the way ROM's and PROM's are implemented is different therefore the implementation of PROM's are not equal to the implementation of the ROM's but you are wrong since the acronym is in no way trying to address how the memory in implemented - only how it is used.
Spend a bit more time thinking and less time doing victory dances.
And I've already told you the lineage of the term in the later products, yet you still persist.
Are PROM's Read-Only Memory? Yes.
No. You can write, and the technology is different from that a ROM.
Are EPROM's Read-Only Memory? Yes.
No. You can write, and the technology is different from that a ROM.
HINT: The ROM in PROM and EPROM means that same thing as ROM.
HINT: The ROM in PROM and EPROM is an homage only to the ability of the original ROMs to hold data without current. Technically, "non-volatile solid-state memory." They used the term "ROM" to associate with the earlier technology although the newer products weren't ROMs. What resulted is a misnomer, although you know marketing, words don't always describe what an item really is. People tend to use "ROM" in casual usage for all types of non-volatile solid-state memory chips, but it's not factually true in in any case but actual masked ROMs.
