17.1 Description

The SDRAM memory interface is made of:
  • the Universal DDR Memory Controller (UDDRC) and
  • the PHYsical layer interface (DDR3PHY).

The UDDRC receives transactions from the internal buses. These transactions are queued internally and scheduled for access in order to the DDR-SDRAM while satisfying the DDR-SDRAM protocol timing requirements, transaction priorities, and dependencies between transactions.
