Use bank 2, 3, 4 for ddr2: micron MT47H128M16RT-25E:C TR question: 1) only 1 DQS pin marked in pin list, how to handle LDQS and UDOS? 2) The DDR2 DQS pin is differential, but FPGA is single end, h...
Hi,
just read the device manual and pin list thoroughly.
Post #1 is quoting the DQS for x16/x18 column, however as clearly written in the device manual and stated in post #2, DDR2 RAM has to use x8/x9 DQS configuration. There are more DQS pins available for x8/x9, e.g. M7 and T7 in bottom banks B3/B4.
