摘要
MOS capacitors with silicon-implanted oxides were studied for nonvolatile memory applications. It was found that the threshold voltages of these devices were strongly dependent on scanning voltage range for the capacitance-voltage measurements. The writing/erasing capability of these memory devices was also evaluated by applying short voltage pulses with opposite polarities. Excellent cycling and endurance characteristics were observed using +/-16 V programming voltages to at least 10(9) cycles for these Si-implanted memory devices. In addition, only a slight narrowing of threshold voltage window was detected as a function of waiting time after the devices were written/erased. The results suggest that silicon-implanted oxides might be applicable to nonvolatile memory cells.
