Hello All,

As i have used 4Gb DDR3 SDRAM (H5TQ4G63AFR-PBC-448A) in one of my product and while calculating MTBF of that board based on MIL-HDBK-217F-Notice2 i found some issue.

In MIL-HDBK-217F-Notice2 document " Die Complexity Failure Rate - C1 " factor is given only for up to 1M but there is no information for 4GB SDRAM... so i have confused on below two points,

1) is this document is applicable to SDRAM ???
2) how to calculate MTBF for this SDRAM ??

Please help me to solved this out.
