Have you been looking for DDR4 datasheets? Here is a roundup of what’s available online from the memory vendors:
Micron datasheets of their DDR4 4Gbit dies in X4 and X8 widths and in DDR4-2133 and DDR4-2400 speed bins are available here: http://www.micron.com/products/dram/ddr4-sdram#fullPart – Hover over the datasheet icon and then click on “Download PDF” to get them.
Samsung datasheets of the DDR4 4Gbit dies in X4 and X8 widths and in DDR4-2133 and DDR4-2400 speed bins are available here: http://www.samsung.com/global/business/semiconductor/product/computing-dram/catalogue – Click on a part number and then click on the PDF link to get them
SK Hynix datasheets of the DDR4 4Gbit dies in X4, X8 and X16 widths and in DDR4-1600, DDR4-1866, DDR4-2133 and DDR4-2400 speed bins are available here:
http://www.skhynix.com/products/computing/computing.jsp?info.ramCategory=computing&info.ramKind=31&info.eol=NOT&posMap=computingDDR4 – Click on a part number and then click the link under “Technical Data Sheet” to get them.
Of course, this is just what’s public. You may be able to get non-public datasheets for other DDR4 devices by asking the memory vendors directly.
The JEDEC standard for DDR4 is here: http://www.jedec.org/standards-documents/results/jesd79-4%20ddr4
This information is as of the date of writing this blog post – memory vendors may update, add or remove datasheets at any time.
