If they started doing this in 2000, they were a bit ahead of their time. With so much emphasis on low power these days, I think the opportunity has caught up with them.
This passage on their website jumped out at me: "Note that EnerChips used in bare die form are 100x smaller than coin cells and can be placed directly inside Multi Chip Modules or Systems on Chip"
I'd like to see a few MCU vendors integrating these with some of their low-power MCUs. That seems so obvious an application that I don't know why it's not already happening.
