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.
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
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
