A non-volatile memory array includes a semiconductor substrate having a main surface, a first source/drain region and a second source/drain region. The second source/drain region is spaced apart from the first source/drain region. A well region is disposed in a portion of the semiconductor substrate between the first source/drain region and the second source/drain region. A plurality of memory cells are disposed on the main surface above the well region. Each memory cell includes a first oxide layer formed on the main surface of the substrate, a charge storage layer disposed above the blocking oxide layer relative to the main surface of the semiconductor substrate and second oxide layer disposed above the charge storage layer relative to the main surface of the semiconductor substrate. A plurality of wordlines are disposed above the second oxide layer relative to the main surface of the semiconductor substrate. |
