A device includes an interface circuit that receives a serial data stream and converts the serial data stream to parallel data and a data strobe (DQS) signal associated with the parallel data using N-bit header fields inserted into the serial data stream.

Apparatuses and methods for writing data to a memory array are disclosed. When data is duplicative across multiple data lines, data may be transferred across a single line of a bus rather than driving the duplicative data across all of the data lines. The data from the single data line may be provided to the write amplifiers of the additional data lines to provide the data from all of the data lines to be written to the memory. In some examples, error correction may be performed on data from the single data line rather than all of the data lines.
