>The chip achieved a maximum operating speed of 71.4 kHz (at Vdd=3V/Vbias=6V) while consuming a maximum of 134.91 mW. Likewise, the chip can run as low as 10 kHz at 2V while consuming just 11.6 mW.

That's really not that impressive, both in speed and power. You can operate 8Bit MCUs clocked at ~50kHz at 100-200µW.

I wonder what that the technology is good for? IGZO is good for large area electronic with low leakage, so I guess it could be used for sensor arrays and similar where you need distributed circuits. Of course, IGZO is already used for display backplanes.

For digital circuits, silicon will most likely beat it in power and cost even for very small designs.
