Which you don't if you are comparing alternatives to a nonvolatile device.

Or the Ramtron statesaver.

As it happens, I have a cost sensitive application where I need to save just 
two bits of user set information while the power is off. eg. Metric/Imperial 
and user option 1/2.

The Ramtron device would be (almost) perfect. The outputs can be tristated, 
so they can share pins with something else. But I have a couple of pins I can 
spare and a 25LC010 is 10% cheaper and the same footprint so I'll use that. 

If you only need to save a couple of bits of information and are pin limited, it 
could be a useful device. You'll pay more than $0.36 to get EEPROM in an 
equivalent micro

Anyone have a better option in SOT-23 ?

Steve.
