#========= THIS IS THE JARGON FILE, VERSION 2.9.10, 01 JUL 1992 =========#
:write-only memory: n. The obvious antonym to `read-only
   memory'.  Out of frustration with the long and seemingly useless
   chain of approvals required of component specifications, during
   which no actual checking seemed to occur, an engineer at Signetics
   once created a specification for a write-only memory and included
   it with a bunch of other specifications to be approved.  This
   inclusion came to the attention of Signetics {management} only
   when regular customers started calling and asking for pricing
   information.  Signetics published a corrected edition of the data
   book and requested the return of the `erroneous' ones.  Later,
   around 1974, Signetics bought a double-page spread in `Electronics'
   magazine's April issue and used the spec as an April Fools' Day
   joke.  Instead of the more conventional characteristic curves, the
   25120 "fully encoded, 9046 x N, Random Access, write-only-memory"
   data sheet included diagrams of "bit capacity vs. Temp.",
   "Iff vs. Vff", "Number of pins remaining vs. number of socket
   insertions", and "AQL vs. selling price".  The 25120 required a
   6.3 VAC VFF supply, a +10V VCC, and VDD of 0V, +/- 2%.
