The present disclosure relates to a method of manufacturing a semiconductor memory device, the method including: forming isolation layers in trenches dividing active regions of a substrate; depositing a tunnel insulating layer and a charge storing layer on an entire structure including the isolation layers; forming mask patterns on the charge storing layer to cover the active regions and to expose the isolation layers; and etching the charge storing layer by using the mask patterns as an etch barrier, thereby forming charge storing layer patterns on the active regions.
