I'm sure that "a series of metastable SRAM bits" is oversimplifying the design significantly. The ID must not change over the lifetime of the part and over a variety of power-up conditions and temperatures.

I agree. They would have to have a lot of bits and some algorithm that would check that is is close to the original pattern.

Cool technology...I am not sure I understand KRS03 how the power up sequence can change in a lifetime of the product...presumably there is a recommended sequence for this and chip controls it to some extent too

Is this a kind of SRAM-based hardware CAM IC design?
