An integrated circuit includes a sensor that reads a fingerprint and provides data corresponding to the fingerprint to a computation engine coupled to the sensor. The computation engine compares the data to stored data and enables a smart card coupled to the computation engine when the data and the stored data match. The computation engine may include an array of flash memory cells arranged in pairs of rows, where flash memory cells in any one row have sources coupled to a common row line and a plurality of conductance mode neurons each having first and second inputs coupled to first and second row lines forming a respective pair of rows. The neurons are coupled to the flash memory cells through a buffer circuit sets a drain-source voltage of the flash memory cells in the row pair coupled to the neuron.
