Abstract
A memory array includes a plurality of memory pages, each memory page includes a plurality of memory cells, and each memory cell includes a floating gate module, a control element, and an erase element. The floating gate module is disposed in a first well, the erase element is disposed in a second well, and the control element is disposed in a third well. The first well, the second well and the third well are disposed in a deep doped region, and memory cells of the plurality of memory pages are all disposed in the deep doped region. Therefore, the spacing rule between deep doped regions is no longer be used to limit the circuit area of the memory array and the circuit area of the memory array can be reduced.
