A memory includes a plurality of memory cells, a sense amplifier coupled to at least one of the plurality of memory cells, a temperature dependent current generator comprising a plurality of selectable temperature dependent current sources for generating a temperature dependent current, a temperature independent current generator comprising a plurality of selectable temperature independent current sources for generating a temperature independent current, and a summer coupled to the temperature dependent current generator and the temperature independent current generator for combining the temperature dependent current and the temperature independent current to generate a reference current for use by the sense amplifier. A temperature coefficient of the reference current is approximately a same as a temperature coefficient of a memory cell current of at least one of the plurality of memory cells.
