    摘要: A semiconductor memory device having a 3D stacked structure includes: a first semiconductor area with a stacked structure of a first layer having first data and a second layer having second data; a first line for delivering an access signal for accessing the first semiconductor area; and a second line for outputting the first and/or second data from the first semiconductor area, wherein access timings of accessing the first and second layers are controlled so that a first time delay from the delivery of the access signal to the first layer to the output of the first data is substantially identical to a second time delay from the delivery of the access signal to the second layer to the output of the second data, thereby compensating for skew according to an inter-layer timing delay and thus performing a normal operation. Accordingly, the advantage of high-integration according to a stacked structure can be maximized by satisfying data input/output within a predetermined standard.
