3.3.1.1. Hard Memory Controller Features
Feature | Description |
---|---|
Memory standards support | Supports DDR4, DDR5, and LPDDR5 SDRAM. |
Memory devices support | Supports the following memory devices:
|
Interface protocols support |
|
Configurable memory interface width |
|
Maximum rank support | 2 ranks with single slot. |
Burst length support |
|
Efficiency optimization features |
|
Starvation counter | Ensures all requests are served before a predefined time-out period, which ensures that low priority access are not left behind while reordering data for efficiency. |
Bank interleaving | Able to issue read or write commands continuously to "random" addresses. You must correctly cycle the bank addresses. |
On-die termination | In DDR4, the controller controls the on-die termination signal for the memory. This feature improves signal integrity and simplifies your board design. |
Refresh features |
|
Power saving features |
|
Memory features |
|
User ZQ calibration | Long or short ZQ calibration request for DDR4. |
