QDRII+ SRAM
The development board supports five independent QDRII+ SRAM memory devices for
very-high speed and low-latency memory access. Each of QDRII+ has a x18 interface,
providing addressing to a device of up to a 8MB (not including parity bits). The QDRII+
has separate read and write data ports with DDR signaling at up to 550 MHz.
lists the QDRII+ SRAM Bank A, B, C, D and E pin assignments, signal
names relative to the Arria 10 GX device, in respectively.
