All address and command lines are sampled on the cross point of the rising edge of CK and falling edge of CK. A Delay Locked Loop (DLL) circuit is Cross Point driven from the clock inputs and output timing for read operations is synchronized to the input clock. Active High Activates the DDR3 SDRAM CK signal when high and deactivates the CK signal when low. By deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh mode. Enables the associated DDR3 SDRAM command decoder when low and disables the command decoder when high. When the command decoder is disabled, new commands are ignored but previous operations continue. Rank 0 is selected by S0; Rank 1 is selected by S1. Asserts on-die termination for DQ, DM, DQS, and DQS signals if enabled via the DDR3 SDRAM mode register. When sampled at the cross point of the rising edge of CK, signals CAS, RAS, and WE define the operation to be executed by the SDRAM. Reference voltage for SSTL15 inputs. — Selects which SDRAM internal bank of eight is activated. During a Bank Activate command cycle, defines the row address when sampled at the cross point of the rising edge of CK and falling edge of CK. During a Read of Write command cycle, defines the column address when sam.
