4.6.4. Single-Port Controller Operation

The single-port controller increases the performance of memory transactions through command and data re-ordering, enforcing bank policies, combining write operations and allowing burst transfers. Correction of single-bit errors and detection of double-bit errors is handled in the ECC module of the single-port Controller.

SDRAM Interface

The SDRAM interface is up to 40 bits wide and can accommodate 8-bit, 16-bit, 16-bit plus ECC, 32-bit, or 32-bit plus ECC configurations, depending on the device package. The SDRAM interface supports LPDDR2, DDR2, and DDR3 memory protocols.
