Support for DDR2 and DDR SDRAM
64-/72-bit SDRAM data bus. 32-/40-bit SDRAM for DDR and DDR2
Programmable settings for meeting all SDRAM timing parameters
The following SDRAM configurations are supported:
— As many as four physical banks (chip selects), each bank independently addressable
— 64-Mbit to 4-Gbit devices depending on internal device configuration with x8/x16/x32 data
— Unbuffered and registered DIMMs
Chip select interleaving support
Support for data mask signals and read-modify-write for sub-double-word writes. Note that a
read-modify-write sequence is only necessary when ECC is enabled.
Support for double-bit error detection and single-bit error correction ECC (8-bit check word across
64-bit data)
Open page management (dedicated entry for each logical bank)
Automatic DRAM initialization sequence or software-controlled initialization sequence
