The SDRAM address space is organized into banks, rows and columns. The DDRSDRC maps
different memory types depending on the values set in the DDRSDRC Configuration Register.
See
trate the relation between CPU addresses and columns, rows and banks addresses for 16-bit
memory data bus widths and 32-bit memory data bus widths.
The DDRSDRC supports address mapping in linear mode .
Linear mode is a method for address mapping where banks alternate at each last SDRAM page
of current bank.
.
The DDRSDRC makes the SDRAM devices access protocol transparent to the user.
