Side Write Operation

The side write operation begins between 9.185 ms and 9.255 ms. The data written out from the DQS driver is also stored in check_fifo.

The following figure shows the waveform for the side write operation.

Side Write Operation Waveform


Note: The incoming data at dq is edge-aligned to the strobe_io.
