Abstract
A timing circuit for reading from a device comprising multi-level non-volatile memory cells, which circuit comprises a single programmable delay block connected to an input terminal for memory address line transition signals. The delay block drives a counter which feedback controls the discharge through a combinational logic circuit connected to the output terminal of the programmable delay block. A logic output circuit, connected to the output terminal of the delay block and to the counter, generates the timing signals.
