ABSTRACT:
The present invention concerns an auto-saving circuit for programming configuration elements of non-volatile memory cells organized in a cells matrix in a memory device integrated on a semiconductor. The auto-saving circuit is inserted between a first and a second power supply reference voltage and is powered also by programming voltages generated inside the memory device to produce at an output programming signals of the configuration elements. The auto-saving circuit includes a first and a second circuit portion, one for each signal output and each powered by a respective programming voltage and each including a switching network with at least one high threshold transistor and decoupling elements to give inertia to the circuit against electrostatic discharges or accidental power supply variations.
