<p>The present disclosure relates to reading and calibrating of multilevel programmable threshold transistor arrays. A system includes a voltage generator (106), current sensing amplifiers (22) and a control module (102). The voltage generator outputs a first voltage, which is generated based on received code words, to a first word line that communicates with N transistors (14) each having programmable threshold voltages, where N is an integer greater than 1. The current sensing amplifiers (22) sense currents through the N transistors via N bit lines, respectively, and generate control signals when current through a corresponding one of the N transistors is greater than or equal to a predetermined current. The control module generates measured values of the threshold voltages of the N transistors by compensating the ones of the code words based on at least one of a position of the corresponding ones of the N transistors and a temperature.</p> |
