Abstract
A memory device having: a cross-point memory array; a current supply circuit adapted to supply a programming current to a selected row line of the array during a programming operation to change the resistive state of a selected memory cell coupled between the selected row line and a selected column line of the array; a leakage current detection circuit coupled to the column lines except the selected column line and adapted to detect leakage currents during the programming operation; and a current limit generation circuit adapted to generate a current limit based on the sum of the leakage currents and on a reference current, and to supply the current limit to the current supply circuit to limit the programming current.
