Abstract
Devices and methods include receiving write command at a command interface of the semiconductor device to write data to memory. An external data strobe is received at a data strobe pin of the semiconductor device. The received external data strobe is divided into multiple phases using phase division circuitry to divide the data strobe into multiple phases to be used in writing the data to the memory.
