Abstract
A semiconductor memory apparatus includes: a data output signal transmitter configured to receive a data signal and a data mask signal and transmit a data output signal through a global data line, the data output signal being outputted by determining whether the data signal is masked or not; and a write driver configured to receive the data output signal through the global data line and input the received data output signal to a local data line corresponding to the data output signal.
Claims6
A semiconductor memory apparatus comprising:
- a data output signal transmitter configured to receive a data signal and a data mask signal and transmit a data output signal through a global data line, wherein the data output signal is transmitted if the data signal is not masked;
- and
- a write driver configured to receive the data output signal through the global data line and input the received data output signal to a local data line,
- wherein the data output signal transmitter comprises:
- a data input strobe signal generation unit configured to be enabled by a write enable signal and generate a data input strobe signal;
- a data buffer unit configured to receive the data signal and buffer the received data signal;
- a data mask buffer unit configured to receive the data mask signal and buffer the received data mask signal;
- and
- a data masking determination unit configured to receive the data input strobe signal, the data signal and the data mask signal, and determine whether the data signal is masked or not.
