Talk:Read-only memory

message: The paragraph about game emulation ROMs probably shouldn't be in this article; they aren't actually read-only memory. --Dinojerm
:Hmm, I suppose you're right, but also consider that the emulation ROMs is extracted/copied from the actual ROMs in the case of cartridge games -- this should be mentioned in the article. --Wernher 09:30, 10 Dec 2004 (UTC)
thread_title: Game emulation ROMs not really ROMs

message: Just regarding my recent revert from Read-Only Memory to Read-only memory in the article's emphasised title phrase: that is the WKP policy,actually. Cf. also a very large amount of similar articles. --Wernher 02:18, 17 Apr 2005 (UTC)
thread_title: Lower-case article title Wikipedia 'policy'

message: The article currently contains the following statement:
:With ROM, the entire chip must be written at the entire chip must be written at once. Changing just one bit requires the whole chip to be erased and re-written with the new data.
Generally, speaking, this is wrong. Most programmable ROM designs (that is, not factory-programmed masked ROMs) allow you to blow bits individually, it's just that you can only blow them in one direction. For example, a certain technology xPROM may be erased to all zeroes or come from the factor as all zeroes, and you can blow ones into it, but you can't individually convert those bits back to zeroes and it for non-erasible PROMs it isn't possible to convert them back to zeroes at all. (Once the fuse or antifuse is blowm its blown.) And a few ROMs allow bidirectional blowing, but the writing process is much slower than the reading process, unlike RAM.
We should work on making the statement more-accurate. I'll do it if I get the time, but please feel free to beat me to it. ;-)

thread_title:  Writeable ROM 

message: I think that if a reader was completely unfamiliar with the concept of ROM, the current lead would be jarring. It somehow seems to assume a greater familiarity with the concept of ROM than an article on ROM should. I'm not sure how to fix it. --Steven Fisher 22:19, 29 December 2006 (UTC)
thread_title:  Lead assumes familiarity? 

message: "P2ROM" is mentioned in the Sharp Zaurus article.
I thought it was a typo, but a brief Google leads me to
"Technology Analysis: Oki P2ROM to Replace Mask ROM, Flash EEPROM"
by Motoyuki Oishi 2003.
which says:
"... equipment manufacturers are turning to production-programmed read-only memory (P2ROM) instead of mask ROM or Flash electrically-erasable programmable ROM (EEPROM) for program storage."
What is "production-programmed read-only memory (P2ROM)"? What should we say about it in this Read Only Memory article? --68.0.124.33 (talk) 16:49, 15 October 2008 (UTC)
thread_title:  P2ROM 

message: i would suggest, that in order to eliminate confusion about the arrangement and inparticular view of computer memory,
all memory types, should be created under a "computer memory types" label instead of being represented each one individualy.
the differences between memory type acronym's should be noted as the difference between their functionalities & technical structure and not only by "symbolic means"..
there might be a need also, to view a sketch of any of their technical designs, in order for the viewer to understand their meaning in a profounder way.☺  —Preceding unsigned comment added by 62.0.187.203 (talk) 00:21, 16 February 2009 (UTC)
thread_title:  SUGGESTION 

message: The "Terminology" section is useless since the section "Types of ROMs" already lists the same content. "Terminology" should be eliminated. It would be nice to introduce a sample schematic for a ROM.  ICE77 (talk) 07:11, 17 November 2009 (UTC)
replies: text: You mean the schematic for the inside of a ROM?  Otherwise the schematic for a ROM is a rectangle with inputs on one side, and outputs on the other.  Otherwise, a mask ROM is a 2D array of diodes which can be connected, or not, between row lines and column lines.  One row is selected, the bits come out, and the appropriate bits selected for the output. Gah4 (talk) 01:57, 3 October 2020 (UTC)
