Sample position A: data are sampled on the expected edge of MEM_CLK, the MDQS signal indicate the valid data
Sample position B: data are sampled on a later edge of MEM_CLK, SDRAM controller is waiting for the valid MDQS signal
NOTE: Control Signals signals are composed of RAS, CAS, MEM_WE, MEM_CS, MEM_CS1 and CLK_EN
