Abstract: A low-power reading reference circuit for split-gate flash memory includes at least a pair of first reference cell and a second reference cell, which provides a reading reference current to regular cells of the split-gate flash memory. A first floating gate of the first reference cell and a second floating gate of the second reference cell are connected to an output of a logic circuit. The logic circuit receives at least one external state signal to determine whether the split-gate flash memory is ready to switch to reading mode or not, and then switches the first floating gate and the second floating gate between the state of activated and deactivated, so as to activate the first reference cell or the second reference cell to provide the reference current.
