Abstract

A characteristic of new waveform, called a negative waveform, was studied during reset and address periods. IR distribution, black luminance and time delay were measured to compare the negative waveform with the conventional positive waveform. Based on the analysis of IR measurement, the negative waveform could accumulate more wall charges than the positive waveform. Also the black luminance of negative waveform was lower than that of positive waveform under the same bias and ramp-slope conditions. During address period, the discharge time lag was measured. The negative waveform was showed 0.25 us faster formative time lag and 0.1 us faster average time lag than those of positive waveform.
