    • A method of reading an NVM cell structure formed on a deep well of N-type semiconductor material, wherein the NVM cell structure includes a PMOS transistor formed in an N-type well, the PMOS transistor including spaced-apart p-type source and drain region defining an n-type cannel region therebetween, an NMOS transistor formed in a P-type well that is adjacent to the N-type well, the NMOS transistor including spaced-apart n-type source and drain regions defining a p-type channel region therebetween, a conductive floating gate that includes a first section that extends over the n-type channel region of the PMOS transistor and is separated therefrom by intervening dielectric material and a second section that extends over the p-type channel region and is separated therefrom by intervening dielectric material, and a conductive control gate formed over at least a portion of the second section of the floating gate and is separated therefrom by intervening dielectric material, the method comprising: biasing the deep N-type well at a preselected read voltage; holding the source region of the PMOS transistor at the read voltage; holding the drain of the PMOS transistor at ground; and holding the control gate at ground for a preselected read time.
