Rev. 1.0 Unbuffered DIMM datasheet DDR3L SDRAM 7. Input/Output Functional Description Symbol Type Function CK and CK are differential clock inputs. All the DDR3 SDRAM addr/cntl inputs are sampled on the crossing of positive CK0-CK1 SSTL edge of CK and negative edge of CK. Output (read) data is reference to the crossing of CK and CK (Both directions of CK0-CK1 crossing) Activates the SDRAM CK signal when high and deactivates the CK signal when low. By deactivating the clocks, CKE low CKE0-CKE1

Rev. 1.0 Unbuffered DIMM datasheet DDR3L SDRAM 7.1 Address Mirroring Feature There is a via grid located under the DRAMs for wiring the CA signals (address, bank address, command, and control lines) to the DRAM pins. The length of the traces from the vias to the DRAMs places limitations on the bandwidth of the module. The shorter these traces, the higher the bandwidth. To extend the bandwidth of the CA bus for DDR3 modules, a scheme was defined to reduce the length of these traces. The pins o
