SDRAM

0x70
The Initialize Memory Command configures the DDR2
SDRAM for access by the FPGA. The memory cannot
be accessed without being initialized.
IMPORTANT NOTE ON DDR2 SDRAM DATA ACCESS:
Writes and reads made to and from the DDR2 SDRAM using the reference design on the
DLP-HS-FPGA3 module are always performed 4 bytes at a time due to the fact that the device is
configured for a burst length of four. What this means is that Column Address Bits 0 and 1 only
change the order of the read or write bytes; they still refer to the same 4 bytes. Therefore, to
increment the DDR2 SDRAM address for consecutive memory locations, the column address must be
incremented by 4.
Incrementing the column address by anything less than 4 simply changes the order in which the 4
bytes specified by Column Address 9:3 are written to the memory or returned to the user.
