    • An Assisted Charge (AC) Memory cell comprises a transistor that includes, for example, a p-type substrate with an n+ source region and an n+ drain region implanted on the p-type substrate. A gate electrode can be formed over the substrate and portions of the source and drain regions. The gate electrode can comprise a trapping structure. The trapping structure can be treated as electrically split into two sides. One side can be referred to as the “AC-side” and can be fixed at a high voltage by trapping electrons within the structure. The electrons are referred to as assisted charges. The other side of can be used to store data and is referred to as the “data-side.” The abrupt electric field between AC-side and the data-side can enhance programming efficiency.
    • 辅助充电(AC)存储单元包括晶体管,其包括例如p型衬底,其具有n +源极区域和n +漏极区域注入在p型衬底上。 栅电极可以形成在衬底上以及源区和漏区的部分之上。 栅电极可以包括捕获结构。 捕获结构可以被电分为两侧。 一侧可以称为“AC侧”,并且可以通过在结构内捕获电子而将其固定在高电压。 电子被称为辅助电荷。 另一边可以用来存储数据,被称为“数据端”。 AC侧和数据侧之间的突发电场可以提高编程效率。
