It looks like someone has revived the Signetics brand name and is using it to promote a new type of memory.

Isn't that the "Old DS" , dated 1972 in bottom.

 

ISTR having seen the Write Only Mem , datasheet several times during the years.

Yes, I have a Signetics spec sheet for WOM (Write Only Memory) from the early 1970s.

 

As I recall, it was one of those "April Fools Day" things. Got them a lot of press. Didn't save the company, though.

Actually, my first computer had a form of WOM, a small ram chip that was used to extend the ram address space from 64k to 1MB.

Normally high memory addresses were used for ROM, so placing this "ram" at the high address made it write only, as its data lines drove the extended memory address bus.

Anyway, guess what was old is new again!

I came across this entry while studying data books to get an overview of the electronics field after graduating from an electric engineering technician program in the mid 1980s.   I was stumped and read it over and over trying to understand what was going on.  Eventually after a long time I realized that it was a parody inserted in the data book as a subtle joke.   I don't think that anyone has done anything like it since then.   

 

There was a company that used to classify its op-amps as: normal, fast, and damn fast in its manuals.

I think that was National Semi.

The Internet Engineering Task Force (IETF) which publishes their

standards in documents called RFCs (Request for Comment) has

a long history of publishing fake specifications on April 1st. RFC

748 from 1978 is the earliest one I could find.

I forgot about that memory chip!  I should have remembered to get one, or at least print the datasheet.

 

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

it looks like some one has re-done the datasheet.

IIRC the original 1972 datasheet looked completely genuine in its set-up with respect to text and pictures, This one has a lot of bogus parameters which will make you think it is fake immediately.
