Abstract
The present disclosure describes a memory structure including a memory cell array. The memory cell array includes memory cells and first n-type wells extending in a first direction. The memory structure also includes a second n-type well formed in a peripheral region of the memory structure. The second n-type well extends in a second direction and is in contact with a first n-type well of the first n-type wells. The memory structure further includes a pick-up region formed in the second n-type well. The pick-up region is electrically coupled to the first n-type well of first n-type wells.
