Abstract
Methods of forming buried bit lines in a non-volatile memory device can include forming impurity regions in a substrate of a non-volatile memory device to provide immediately neighboring buried bit lines for the device and then forming a shallow trench isolation region in the substrate between the immediately neighboring buried bit lines to substantially equalize lengths of the immediately neighboring buried bit lines.
