Every two adjacent NAND-based NOR flash cells in a column share a common source node which is connected to a common source line through a diode. The source line may be made of a metal layer and is in contact directly with the source node or through an ohmic contact to form a Schottky barrier diode. The source line may also be made of a polysilicon or metal layer and connected to the source node through a pillar-structured polysilicon diode and a conduction layer. The diode may also be formed in the source node by enclosing a P/N+ junction diode in a heavily N+ doped region of the source node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"NAND-based 2T2b NOR flash array with a diode connection to cell's source node for size reduction using the least number of metal layers","description":"A NAND-based NOR flash memory array has a matrix of NAND-based NOR flash cells arranged in rows and columns.
