Preliminary Data Sheet
DDR SDRAM Write Operation
The rising edge of MemClkOut aligns with the first rising edge of the DQS signal on writes. The following data is
generated by means of simulation and includes logic, driver, package RLC, and lengths. Values are calculated
over best case and worst case processes with speed, junction temperature, and voltage as follows:
Note: In the following tables and timing diagrams, minimum values are measured under best case conditions and
maximum values are measured under worst case conditions. The timing numbers in the following sections are
obtained using a simulation that assumes a model as shown in Figure 6.
