摘要： An asymmetrically doped memory cell has first and second N+ doped junctions on a P substrate. A composite charge trapping layer is disposed over the P substrate and between the first and the second N+ doped junctions. A N− doped region is positioned adjacent to the first N+ doped junction and under the composite charge trapping layer. A P− doped region is positioned adjacent to the second N+ doped junction and under the composite charge trapping layer. The asymmetrically doped memory cell will store charges at the end of the composite charge trapping layer that is above the P− doped region. The asymmetrically doped memory cell can function as an electrically erasable programmable read only memory cell, and is capable of multiple level cell operations. A method for making an asymmetrically doped memory cell is also described.

摘要： A memory cell with a charge trapping structure is programmed using refill cycles that include a program pulse followed by a charge balancing pulse that causes ejection of electrons from the charge trapping structure. The refill cycle causes a blue spectrum shift in the charge trap distribution in the charge trapping structure. The algorithm includes program verify operations after the program pulse, and completes when a successful program verify operation occurs after a number of refill cycles. The charge retention properties can be greatly improved by these refill cycles.

摘要： A non-volatile memory cell comprising a substrate, a charge-trapping layer, a control gate, a first conductive state of source and drain, a lightly doped region and a second conductive state of pocket-doped region. The charge-trapping layer and the control gate are disposed over the substrate. A dielectric layer is disposed between the substrate, the charge-trapping layer and the control gate. The source and drain are disposed in the substrate on each side of the charge-trapping layer. The lightly doped region is disposed on the substrate surface between the source and the charge-trapping layer. The pocket-doped region is disposed within the substrate between the drain and the charge-trapping layer. Because there are asymmetrical configuration and different doped conductive states of implant structures, the programming speed of the memory cell is increased, the neighboring cell disturb issue is prevented, and the area occupation of the bit line selection transistor is reduced.
摘要翻译：一种非易失性存储单元，包括衬底，电荷俘获层，控制栅极，源极和漏极的第一导电状态，轻掺杂区域和第二导电状态的袋掺杂区域。电荷捕获层和控制栅极设置在衬底上。电介质层设置在基板，电荷俘获层和控制栅极之间。源极和漏极设置在电荷俘获层的每一侧上的衬底中。轻掺杂区域设置在源极和电荷捕获层之间的衬底表面上。掺杂阱区域设置在漏极和电荷捕获层之间的衬底内。由于存在不对称配置和掺杂导体状态的不同，存储单元的编程速度增加，从而防止了相邻单元的干扰问题，并减少了位线选择晶体管的占用面积。
