Memory
On the
Komodo CXP
there are 2 memory interfaces, this section describes those interfaces and also
signal names, types, and connectivity relative to the Arria V GZ. The starter board has the following
memory interfaces:
16Gb DDR3 on-board SDRAM with 64bit data width, 1066 rate compatible.
Up to 128Gb DDR3 SODIMM with 64bit data width, 1066 rate compatible (J11).
If any, or both, of those memories are used, the RZQ signal must be connected to the DDR3 control
IP. If only the on-board DDR3 memory is used, this signal should be connected to the DDR3 IP that
controls this memory, as shown in the following figure:
