Semiconductor device

摘要

Disclosed herein is an apparatus that includes: a first terminal configured to receive a serial write data signal that includes at least four bits transferred in series with each other; a second terminal configured to receive a data strobe signal; a control circuit configured to produce a plurality of internal data strobe signals in response to the data strobe signal; and a serial-to-parallel conversion circuit configured to respond to the data strobe and internal data strobe signals to convert the serial write data signal into a parallel write data signal that includes at least four bits produced in parallel to each other.

1. An apparatus comprising:
a first terminal configured to receive a serial write data signal that includes at least four bits transferred in series with each other; a second terminal configured to receive a data strobe signal; a third terminal configured to receive a write command; a fourth terminal configured to receive a clock signal; a command signal generating circuit configured to produce a first write enable signal in response to the write command and the clock signal, wherein the first write enable signal is less in frequency than the clock signal; a control circuit configured to produce a plurality of internal data strobe signals in response to the data strobe signal; and a serial-to-parallel conversion circuit configured to respond to the data strobe and internal data strobe signals to convert the serial write data signal into a parallel write data signal that includes at least four bits produced in parallel to each other.
