I installed the Automatic Program Load option on my Data General Nova 1200's CPU board. It uses a weird open-collector N82S23N Programmable Read-Only Memory. Not an EPROM, just PROM -- you get ONE shot to program it right and if you screw it up, it's ruined forever. All that's needed to install it is a pair of sockets (or directly soldering it into the PCB, but I wouldn't recommend that).

The global proliferation of embedded systems across industrial, automotive, and consumer electronics is significantly driving demand for One Time Programmable (OTP) EPROM solutions. These non-volatile memory chips provide firmware storage for microcontroller-based devices where data retention is critical. With the industrial IoT market projected to reach $350 billion by 2030, the need for reliable firmware storage solutions has intensified. OTP EPROMs offer distinct advantages in these applications because they maintain programmed data without power while preventing unauthorized modifications – crucial for security-sensitive embedded applications.

Cost-Effectiveness in High-Volume Manufacturing Accelerating Market Penetration

OTP EPROM technology continues gaining traction due to its economic advantages in high-volume production environments. Unlike flash memory that requires additional process steps, OTP chips utilize standard CMOS fabrication techniques, resulting in 15-20% lower production costs at scale. This cost benefit becomes particularly compelling for devices requiring less than 1MB of permanent code storage. Leading manufacturers are leveraging this advantage to displace EEPROM solutions in price-sensitive applications like smart sensors, IoT edge devices, and automotive control modules where firmware updates aren't required.

MARKET RESTRAINTS

Proliferation of Flash Memory Technologies Restricting Market Expansion

The OTP EPROM market faces intensifying competition from rapidly advancing flash memory solutions offering higher densities and reprogrammability. NOR flash memory prices have decreased by approximately 8% annually over the past five years while densities have increased exponentially. This pricing pressure creates significant challenges for OTP EPROM adoption in applications where occasional firmware updates may be required. Furthermore, the growing availability of low-cost microcontrollers with integrated flash memory is diminishing the need for external OTP solutions in many cost-sensitive designs.

EEP ROM is some masterful typography. It's cute and technically accurate!

See at first we had mask ROMs: this is where you have a chip that's designed from the start to only have some specific data on it. That's why it's Read Only Memory: it's memory, but you can only read it. This is what, like, NES games were built on: the game is on the ROM chip, and can't be changed.

Then someone figured out you could make the chip so that it starts out blank, then you can program it once (like burning a CD-R), so we called these Programmable ROMs: PROMs.

And then another clever engineer worked out how to make them re-erasable, by using ultraviolet light that causes the bits to weaken. You have to take out the chip, expose it in a special box (you can't just have a flashlight, because UV light will give you skin cancer and sunburns on your eyes), then program it and put it back in. But hey, it's erasable and reusable now! This is how a lot of games were developed for cartridge consoles: you'd have a special cartridge that has exposed chips, which you program and put back in the console to test. This new erasable and programmable ROM was obviously called the Erasable Programmable ROM, or an EPROM.

But then a very clever trick was figured out: if you use quantum mechanical effects you can trap charge in a tiny cell and get it out using quantum tunneling, which means you can erase it in-situ! Now you have a reusable (for a while) rewritable chip, so it was called Electrically Erasable Programmable Read Only Memory: EEPROM!

But by putting a space in it, they made it an EEP ROM, which is a much cuter name.

BTW EEPROMs are what flash memory grew out of: this is a 1985 SD card.

To me, an AI's "binary/trinary/qubits code" is that AI's soul, so to speak. Is it possible that someone can create a "computer virus" that can attack/erase all of a "computer's/AI's ""binary/trinary/qubits code" & ""Boot media" program(s)"""?

If such a computer virus is able to be created, it "is or would be useful" in military warfare, but problematic in the wrong hands. For example, in the wrong hands, someone could make someone else's Tesla car stranded, leaving the "Tesla car and its owner" stranded. The owner might find a means to no longer be stranded but I don't know "what would happen regarding that Tesla car".

There have been multiple versions of ROM (Read-only Memory) over the years.

The original type of ROM had the memory contents physically encoded directly in the circuit architecture at the time of fabrication. This type of ROM can't be rewritten.

The next type of ROM was PROM (Programmable ROM) which can be written EXACTLY once by using high voltage to burn out parts of the circuit to encode the contents in the architecture of the circuit.

Then came EPROM, which was kind of like PROM, except you could reset the entire memory chip by exposing the chip to strong ultraviolet light, and then rewrite it from scratch.

Then came EEPROM, which allows reset and rewrite of individual pieces of the memory. Flash memory is a type of EEPROM. It is not really "read only memory" at all, because it is possible to repeatedly rewrite it, although in practice it is often used in systems that do not have the capability to rewrite it, either because rewriting is not implemented in the hardware or software. It can be written to, and then erased but does not need current to keep the data, which means when you shut your computer off, EEPROM keeps the information unlike RAM. So why not always use EEPROM? Because it's much much MUCH slower than RAM.

REALLY, at this point, the difference between RAM and ROM is that RAM is volatile and ROM is persistent - when you turn the computer off, all the data stored in RAM disappears, but the data stored in ROM doesn't.

Is it 100% impossible to write to read only memory? Could a hacker, for example, put a virus to a "read only factory reboot partition" of your hard drive?

So no, it isn't 100% impossible to write to read only memory, depending on the type of read only memory.

The "read only factory reboot partition" of a hard drive isn't even ROM, though. It's just normal space on the hard drive that is tagged "gee, you really shouldn't write anything here, because this is important," and most computer programs respect those tags and won't write to that data. If you have a piece of software that doesn't care about the read-only tags, then it will be perfectly happy to do anything you want to that partition.

As far as viruses through actual ROM devices, there was a pretty big uproar a while ago because someone figured out how to propagate viruses through the firmware chips (which are ROM) of USB devices and controllers. As far as I know, there aren't any real viruses in the wild using this method, but also as far as I know, the vulnerability hasn't been fixed.
