A semiconductor device includes an alignment data generation circuit aligning first and second latch data generated from a first group of input data in synchronization with a first internal strobe signal, outputting the aligned first and second latch data as first alignment data, aligning a first and second latch data generated from a second group of the input data in synchronization with a second internal strobe signal, and outputting the aligned first and second latch data as second alignment data. The semiconductor device includes a write data generation circuit generating first and second write data from the first and second alignment data in synchronization with a latch clock after the start of a first operation mode and generating the first and second write data from the first alignment data in synchronization with the latch clock after the start of a second operation mode.

Semiconductor device for performing data alignment operation

A memory device includes a first comparison circuit suitable for comparing read data read from a plurality of memory cells with write data written in the memory cells and outputting a comparison result, a path selection circuit suitable for transferring selected data selected among the read data and test data as read path data based on the comparison result of the first comparison circuit, and an output data alignment circuit suitable for converting the read path data into serial data to output the serial data as output data.

Memory device and test operation thereof

A semiconductor device includes a control circuit configured to receive a clock and generate first to fourth internal clocks which have different phases, and generate first to fourth masking clocks from a latency signal in synchronization with the first internal clock and the second internal clock depending on a mode signal; and a signal mixing circuit configured to output the first to fourth internal clocks as first to fourth strobe signals during enable periods of the first to fourth masking clocks.
