40 V high voltage arbitrary waveform pulse generator at automatic parametric tester

This paper introduces the development work of high voltage pulse capability of Keithley automatic parametric tester (APT). To meet the market demand for high voltage (40 V) function/arbitrary waveform pulse generator, Keithley Instruments developed new pulse generator that implements both features of high voltage and function/arbitrary pulse waveform within single instrument. Integrated this new pulse generator into APT, provides flash memory manufacturer a powerful tool to measure flash memory device in both Fab and Lab environment more easily and quickly than ever before. Flash memories are penetrating a wide variety of markets and products. Application examples are memory cards, MP3 audio players, cell phones, and digital cameras. This development work is driven by the demand of flash memory tests, more specifically, multilevel-flash-memories tests.
