The Universal DDR Memory Controller (uMCTL) is a multi-port memory controller which accepts memory access requests from up to 32 application-side host ports. Application-side interfaces can be connected to the uMCTL either through the standard AMBA AXI/AHB bus interfaces or via Synopsys custom-defined extended native interface (ENIF). The configuration registers for the uMCTL are programmed via the AMBA 2.0 APB software interface.

The uMCTL connects to DDR PHYs via a DFI 2.1 interface to create a complete memory interface and control solution. The controller includes software configuration registers, which are accessed through an AMBA 2.0 APB interface.

Highlights

For new designs or for designs with higher speed requirements and greater RAS features, consider Synopsys’s Enhanced Universal DDR Memory Controller (uMCTL2)
Select a complete multi-ported enhanced Universal DDR Memory Controller offering up to 16 host ports, or join a third-party scheduler to a single-port enhanced Universal Memory Controller or Universal Protocol Controller
Support for JEDEC standard DDR2, DDR3, LPDDR/Mobile DDR, LPDDR2 and LPDDR3 SDRAMs
Compatible with all Synopsys DDR PHYs (excluding DDR2/DDR PHYs)
DFI 2.1 compliant interface to DDR PHY (DFI 3.1 is backward compatible with DFI 2.1)
Data rates up to 2133 Mbps in 1:2 frequency ratio, using a 533 MHz controller clock and 1066 MHz memory clock (dependent on process)
Data rates up to 1600 Mbps in 1:1 frequency ratio, using a 800 MHz controller clock and 800 MHz memory clock (dependent on process)
