Abstract: Provided is a memory device including a substrate, a source region, a drain region, a source contact, a drain contact, at least two stack gates, and at least two selection gates. The source region and the drain region are both located in the substrate. The source contact is located on the source region and the drain contact is located on the drain region. A bottom area of the drain contact is greater than a bottom area of the source contact. The stack gates are located on the substrate at two sides of the source region respectively. The selection gates are located on the substrate at two sides of the drain region respectively. A distance between the selection gates located at two sides of the drain region is greater than a distance between the stack gates located at two sides of the source region.
