Design and Fabrication of a Versatile Testing System for MNOS.

摘要

The versatile testing system for MNOS is a programmable generator that generates wavetrains necessary to measure writing characteristics,memory retention,and degradation information. It is capable of generating both positive and negative pulses of different amplitudes and widths. The generator also has the capability of increasing the widths of predetermined pulses after each wavetrain has been generated,and halting operation when a predetermined width has been reached. It functions as an independent unit;once programmed it is capable of generating the required wavetrains,and measuring the threshold voltage of a test device without assistance from any external device.
