    • The subject invention provides systems and methods that facilitate formation of semiconductor memory devices comprising memory cells with one or more injecting bilayer electrodes. Memory arrays generally comprise bit cells that have two discrete components; a memory element and a selection element, such as, for example, a diode. The invention increases the efficiency of a memory device by forming memory cells with selection diodes comprising a bilayer electrode. Memory cells are provided comprising bilayer cathodes and/or bilayer anodes that facilitate a significant improvement in charge injection into the diode layers of memory cells. The increased charge (e.g. electrons or holes) density in the diode layers of the selected memory cells results in improved memory cell switching times and lowers the voltage required for the memory cell to operate, thereby, creating a more efficient memory cell.
    • 本发明提供了便于形成包括具有一个或多个注入双层电极的存储器单元的半导体存储器件的系统和方法。 存储器阵列通常包括具有两个分立组件的位单元; 存储元件和选择元件,例如二极管。 本发明通过形成具有包括双层电极的选择二极管的存储单元来提高存储器件的效率。 提供包含双层阴极和/或双层阳极的存储器单元,其有助于电荷注入到存储器单元的二极管层中的显着改进。 所选择的存储器单元的二极管层中的增加的电荷(例如电子或空穴)密度导致改善的存储单元切换时间并降低存储器单元操作所需的电压,从而创建更有效的存储单元。
