write-only memory
(foldoc) | write-only memory
WOM
1. (WOM) The obvious antonym to "{read-only
memory}" (ROM).
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%.
2. bit bucket.
