Disclosed is a matching circuit of a laminated duplexer connected to an antenna terminal while being connected between transmitting and receiving filters to match the transmitting and receiving filters with the antenna terminal, the matching circuit being configured to reduce the physical length of each conductor pattern thereof, thereby being capable of achieving an improved miniaturization thereof. The matching circuit includes a transmitting matching unit constituted by a conductor pattern electrically connected to an antenna electrode connected to the antenna terminal while being electrically connected to the transmitting filter, a first ground electrode vertically spaced apart from the conductor pattern, a receiving matching unit constituted by a conductor pattern electrically connected to the antenna electrode and the receiving filter, and a second ground electrode vertically spaced apart from the conductor pattern of the receiving matching unit. A laminated duplexer provided with the matching circuit is also disclosed. In accordance with the configuration of the matching circuit, it is possible to achieve a reduction in insertion loss, an improvement in the reflection characteristics of an associated antenna, and, thus, an improvement in bandpass characteristics.

A nonvolatile memory device with a memory cell array including a plurality of memory cells coupled to first through M-th wordlines and first through N-th bitlines (M>2, N>2), and a page buffer circuit including first through N-th page buffers that are coupled to the first through N-th bitlines, respectively, and generate first through N-th output data, respectively. A K-th page buffer includes first through L-th latches which generate read data by sampling a voltage of a K-th output line, which is discharged through a K-th bitline, at different sampling timings after a read voltage is applied to a P-th wordline (K≦N, L>1, P≦M). The K-th page buffer outputs the first output data if an error in the read data of the first latch is correctable.

A memory device is provided as follows. A memory cell array includes a plurality of memory cells, and the plurality of memory cells are divided into a first memory group and a second memory group. A first page buffer group is coupled to the first memory group and includes a plurality of first page buffers. A second page buffer group is coupled to the second memory group and includes a plurality of second page buffers. The first page buffer group performs a first data processing operation on data stored in the first page buffer group and stores a result of the first data processing operation. The second page buffer group performs a second data processing operation on data stored in the second page buffer group and stores a result of the second data processing operation. The first and second data processing operations are performed at substantially the same.
