Abstract
A data input circuit includes a valid strobe signal generation circuit and a data strobe signal counter. The valid strobe signal generation circuit is configured to remove a pulse of an internal strobe signal generated and generate a valid strobe signal. The pulse may have been generated during a preamble period. The data strobe signal counter is configured to count the valid strobe signal according to burst length information and generate a write latch signal for aligning data at a time of a write operation.
Claims22
A data input circuit comprising:
- a valid strobe signal generation circuit configured to remove a pulse in an internal strobe signal and generate a valid strobe signal, wherein the pulse is generated during a preamble period;
- and
- a data strobe signal counter configured to count the valid strobe signal according to burst length information and generate a write latch signal for aligning data at a time of a write operation.
A data input circuit comprising:
- a data strobe signal buffer configured to buffer a data strobe signal and generate a first internal strobe signal and a second internal strobe signal;
- and
- a valid strobe signal generation circuit configured to remove a pulse of the first internal strobe signal and generate a valid strobe signal, wherein the pulse is generated during a preamble period.
