摘要
A NAND type flash memory for increasing data read/write reliability includes a semiconductor substrate unit, a base unit, and a plurality of data storage units. The semiconductor substrate unit includes a semiconductor substrate. The base unit includes a first dielectric layer formed on the semiconductor substrate. The data storage units are adjacent to each other and formed on the first dielectric layer. Each data storage unit includes at least two floating gates formed on the first dielectric layer, a second dielectric layer formed on the first dielectric layer and between the two floating gates, an inter-gate dielectric layer formed on the two floating gates and the second dielectric layer, at least one control gate formed on the inter-gate dielectric layer, and a third dielectric layer formed on the first dielectric layer and surrounding and tightly connecting with the two floating gates, the inter-gate dielectric layer, and the control gate.
