Software Interface/SDRAM Organization, Address Mapping

The SDRAM address space is organized into banks, rows, and columns. The SDRAMC allows mapping different memory types according to the values set in the Configuration register (SDRAMC_CR).

The SDRAMC makes the SDRAM device access protocol transparent to the user. The following tables illustrate the SDRAM device memory mapping seen by the user in correlation with the device structure. Various configurations are illustrated.
