Ahm ... having worked with a DDR3 SDRAM protocol before, the underlying protocol doesn't allow simultaneous reads and writes. As a result, any attempts you make will need to be buffered in order to give the appearance of being simultaneous. Perhaps you should check your FIFO/buffering settings therefore.

FIFO setting as in which IP ?, My master has no Provision for it, I did not see any on the Slave controller either. Please specify.

Thank you
