Part-4
Identifying DDR Module by Chip Labeling
One of the more definite methods of recognizing the configuration of the DDR DIMM module is by identifying the type of chips and their organizations. If the SDRAM chip is made on a major brand name, you should be able to match the unique part number with the manufacturer’s bank of data sheets.See picture below of a typcial chip part number system.

The following table is a summary of all the major DDR SDRAM manufacturers and links to their DDR data sheets. You must note that most of the DDR SDRAM on the market now-a-days are either in the X4 or X8 data bit configurations.
