Re: [N8VEM-S100:1533] OTish: Write Only Memory, Signetics 25120

What does it mean if I remember the original?

I guess I would have to check the datasheet to see if it requires
any special glue logic. A useful enhancement might be to add
a sense wire that would carry back a very small signal if you wrote 
a pattern into the WOM that was different than what was already there.

Of course if the only way to read a bit from the WOM was to overwrite 
it, you would have to rewrite the data after you destroyed it . I believe
that is the core technology required in this case.

You know ROM, RAM but what about WOM?
Look at the Signetics WOM chip, it can fit any circuit.
It's ideal for bit buckets and First-in-never-out registers.

Check the datasheet:


It's been 41 years since this joke, but it still a good laugh.
What's even more funny is that customers were calling for pricing.
