摘要： An operation scheme for operating stably a semiconductor nonvolatile memory device is provided.When hot-hole injection is conducted in the semiconductor nonvolatile memory device of a split gate structure, the hot-hole injection is verified using a crossing point that does not change with time. Thus, an erased state can be verified without being aware of any time-varying changes.Also, programming or programming/erasure is conducted by repeating pulse voltage or multi-step voltage application to a gate section multiple times.
摘要翻译： 提供一种稳定运行半导体非易失性存储器件的操作方案。 当在分裂栅极结构的半导体非易失性存储器件中进行热空穴注入时，使用不随时间变化的交叉点来验证热孔注入。 因此，可以验证擦除状态，而不知道任何时变变化。 此外，通过将多次脉冲电压或多级电压施加到栅极部分进行编程或编程/擦除。
