| 摘 要： | 通过实验进行了SRAM数据残留机理的研究,建立了数据残留时间与温度的关系.确定了低温下非平衡载流子复合率及扩散速度的降低,是导致SRAM断电后数据残留的主要原因.同时进行了SRAM电参数与数据残留的相关性分析,排除了实验条件下热载流子效应对数据残留特性的影响. |
| 关 键 词： | 数据残留 低温 载流子复合 热载流子效应 |

| Abstract: | The mechanism of data remancence of SRAM is studied by experiment, the relationship between data remanence time and temperature is built. The root cause of data remanence of SRAM is determined which is the decrease of excess-carrier recombination rate and carrier diffusion velocity at low temperature. As well as the relationship between the characteristic of data remanence and electronic parameters is analyzed. The effects of the hot-carrier on the data remanence of SRAM at the experiment condition is exclu... |
