    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 method of determining an optimal reading voltage for reading a two-side non-volatile memory programmed with a threshold voltage Vt is described. A first side of a memory cell is programmed to Vt, and then an I1-Vg curve of the first side and an I2-Vg curve of the second side are measured, wherein Vg is the gate voltage. A Gm1-Vg curve and a Gm2-Vg curve are plotted, wherein Gm1=dI1/dVg and Gm2=dI2/dVg. The optimal reading voltage VgO is determined as the gate voltage at the intersection of Gm1 and Gm2, corresponding to a maximal total current window Wm (=I2(VgO)−I1(VgO)).

    摘要: A memory cell array of dielectric charge trapping memory cells and method for performing program, read and erase operations on the memory cell array that includes bits stored at charge trapping sites in adjacent memory cells. A bit of information is stored at a first charge trapping site in a first memory cell and a second charge trapping site in a second adjacent memory cell. Storing charge at two trapping sites in adjacent memory cells increases data retention rates of the array of memory cells as each charge trapping site can be read to represent the data that is stored at the data site. Each corresponding charge trapping site can be read independently and in parallel so that the results can be compared to determine the data value that is stored at the data site in an array of dielectric charge trapping memory cells.

    摘要: A memory device having a phase change material element with a modified stoichiometry in the active region does not exhibit drift in set state resistance. A method for manufacturing the memory device includes first manufacturing an integrated circuit including an array of phase change memory cells with bodies of phase change material having a bulk stoichiometry; and then applying forming current to the phase change memory cells in the array to change the bulk stoichiometry in active regions of the bodies of phase change material to the modified stoichiometry, without disturbing the bulk stoichiometry outside the active regions. The bulk stoichiometry is characterized by stability under the thermodynamic conditions outside the active region, while the modified stoichiometry is characterized by stability under the thermodynamic conditions inside the active region.
