The following pdf is roughly the same as the one linked in the article, but has better formatting/ocr so it tends to be more effective when trolling your favorite EE friends.<p><a href="http://repeater-builder.com/molotora/gontor/25120-bw.pdf" rel="nofollow">http://repeater-builder.com/molotora/gontor/25120-bw.pdf</a>
The concept of WOM isn't completely pointless for non von Neumann architectures, and could even be useful for von Neumann-esque SPMD or MPMD systolic array (<a href="http://en.wikipedia.org/wiki/Systolic_array" rel="nofollow">http://en.wikipedia.org/wiki/Systolic_array</a>) architectures that have strict execution models forced in the core to core wiring. While not completely free form, you would still have instructions and data being stored in the same space, it would be only readable by the individual PU is corresponds to. That PU would not write-back to that same memory, and instead could only write to an adjacent PU's memory, which then would only be readable (and not writable) by that next PU in the line.<p>I've been wanting to implement such an architecture on an FPGA for a while now... may do so over this winter break.
Reminds me of the retro encabulator (which was actually a video, not a data sheet) <a href="https://www.youtube.com/watch?v=NpnEiOOfu1Q" rel="nofollow">https://www.youtube.com/watch?v=NpnEiOOfu1Q</a><p>"The line-up consisted simply of six hydrocoptic marzul vanes so fitted to the ambaphascient lunar wain shaft that side fumbling was effectively prevented."<p>Ahhh, classic.
Perhaps not write-only memory per se, but write-only registers are a pretty common thing if you do any hardware-level programming.<p>Though admittedly this isn't something I've done for a number of years, IIRC both the VGA and the original Sound Blaster had write-only registers which you would use to request some change in state, and some other registers that would reflect the actual current state of the device if/when the request was honoured.<p>Of course these are not write-only in the sense that <i>nothing</i> can read their contents, since they are provided as an interface to some coprocessor like a GPU or a sound chip. That coprocessor can of course read the incoming data. They are more like the hardware equivalent of mutator methods on top of private properties.
