摘要: A method of fabricating a flash memory device using a process for forming a self-aligned floating gate is provided. The method comprises forming mask patterns on a substrate, etching the substrate using the mask patterns as an etch mask to form a plurality of trenches, and filling the trenches with a first insulating layer, wherein sidewalls of the mask patterns remain exposed after filling the trenches with the first insulating layer. The method further comprises forming spacers on the exposed sidewalls of the mask patterns, filling upper insulating spaces with a second insulating layer thereby defining isolation layers, and removing the mask patterns and the spacers.

摘要: In a method of programming a non-volatile memory device, a first voltage is applied to a selected memory cell for programming, and a second voltage is applied to a non-selected memory cell. Before the second voltage rises to a predetermined voltage level, which is less than a program voltage level, the first voltage is greater than the second voltage or the second voltage is maintained at greater than a ground voltage level. Related non-volatile memory devices and memory systems are also discussed.
