Notes:
1. “n” is a row PIC number.
2. The DDR interface is designed for memories that support one DQS strobe up to 15 bits
PICs Associated with
of data for the left and right edges and up to 17 bits of data for the bottom edge. In some
packages, all the potential DDR data (DQ) pins may not be available. PIC numbering
definitions are provided in the “Signal Names” column of the Signal Descriptions table.
