Abstract:
A control gate and word line voltage boosting circuit for twin MONOS, metal oxide nitride oxide semiconductor memory cell comprising:a word line, which is placed over a thin oxide, a control gate-left, which is placed over a nitride implant, in said thin oxide, a control gate-right, which is placed over another nitride implant, in said thin oxide, and a bit-line, which is in diffusion under said oxide, wherein said control gate left and said control gate right forming a 2-bit cell, wherein said 2-bit cell is made up of a left side bit and a right side bit, wherein said left side bit can be selected through application of specific voltages on a neighboring cell's control gate or bit line, different from selected cell's voltages and other selected cell's voltages.
