RLDRAM II
The development board supports a 32Mx18x8 bank CIO RLDRAM II SRAM interface
for very-high-speed sequential memory access. The 18-bit data bus comprises of a
single x18 device with a single address or command bus. This interface connects to the
vertical I/O banks on the bottom edge of the FPGA. The target speed is 533 MHz.
Table 2–54 lists the RLDRAM II pin assignments, signal names, and functions.
