A project log for Self Clocking ROM

There are a few projects that can be implemented with a ROM and need a clock source...

So I was in the shower and had an idea. The idea was to add an LC delay between a data output line and an address input line of a memory chip in order to create the inverter needed for building an oscillator.

Normally I would reject this idea, writing off that that system would find a voltage between logical 1 and 0 that it would stabilize on, but I'd recently been reading RAM datasheets that mentioned they had schmitt triggers on all the inputs....

Could it work?

It would be easy to build a ROM image and do a test. 

An application beyond the basic oscillator test could be a multiplexer for a multi-segment display.
