SDRAM Memory (U39 and U40)
The SDRAM devices (U39 and U40) are 2 Micron MT48LC4M32B2
devices with PC100 functionality and self refresh mode. The SDRAM is
fully synchronous with all signals registered on the positive edge of the
system clock.
The SDRAM device pins are connected to the Stratix II device. An
SDRAM controller peripheral is included with the Stratix II DSP
Development Kit, Professional Edition, and allows a Nios II processor to
view the SDRAM devices as a large, linearly-addressable memory.
