26.3.2.2. Memory Type

These options define the memory type of the AXI-4 On-Chip Memory II
  • Type—
    • RAM (writable)—This setting creates a readable and writable memory.
    • ROM (read only)—This setting creates a read-only memory.*
  • Number of AXI interfaces—
    • Single Interface—This setting creates a memory component with a single AXI-4 agent. Each AXI-4 agent consists of independent read and write channels.
    • Dual Interfaces**—This setting creates a memory component with two AXI-4 agents. Each AXI-4 agent consists of independent read and write channels.
    Note:

    *AXI-4 ROM memory-type exposed both read and write channels. AXI-4 ROM write channel will be terminated internally and any write transaction will not take effect.

    **Dual AXI interfaces for RAM memory type is only supported in Intel® Stratix® 10 and Intel® Agilex™ devices.

  • Block Type—This setting directs the Intel® Quartus® Prime software to use a specific type of memory block when fitting the On-Chip Memory II in the FPGA. There are three settings:
    • Auto—Allows Intel® Quartus® Prime software to choose a type of memory block when fitting the On-Chip Memory in the FPGA. This setting is the best to use because of the constraints on some memory types.
    • M20K—This setting is selected when fitting the On-Chip Memory II in the FPGA.
    • MLAB—This setting is selected when fitting the On-Chip Memory II in the FPGA.
      Note: MLAB does not support AXI-4 dual interface.
