Abstract: A non-volatile memory device comprises a semiconductor substrate of a first conductivity type. An array of non-volatile memory cells is located in the semiconductor substrate and arranged in a plurality of rows and columns. Each memory cell comprises a first region on a surface of the semiconductor substrate of a second conductivity type, and a second region on the surface of the semiconductor substrate of the second conductivity type. A channel region is between the first region and the second region. A word line overlies a first portion of the channel region and is insulated therefrom, and adjacent to the first region and having little or no overlap with the first region. A floating gate overlies a second portion of the channel region, is adjacent to the first portion, and is insulated therefrom and is adjacent to the second region. A coupling gate overlies the floating gate. A bit line is connected to the first region. During the operations of program, read, or erase, a negative voltage can be applied to the word lines and/or coupling gates of the selected or unselected memory cells.

Abstract: An integrated circuit die has a first die pad for receiving a first voltage and a second die pad for receiving a second voltage. The second voltage is less than the first voltage and is generated by a voltage regulator that receives the first voltage. A first circuit which is operable at the first voltage is in the integrated circuit die. A second circuit which is operable at the second voltage is in the integrated circuit die and is connected to the second die pad. The voltage regulator is enabled by a controller.
