Multi level memory architecture

Four level memory architecture (PDF) provides the optimal granularity and efficient area utilization.

  • Up to 520 Kb distributed SelectRAMâ„¢+ memory
    • Each LUT works as a single-port or dual-port RAM/ROM
    • LUTs can be cascaded to build larger memories
    • Flexible memory for FIFOs, and buffers
  • Up to 1.87 Mb embedded block RAM
    • Up to 104 blocks of synchronous 18 Kb block RAM can be cascaded
    • Each 18 Kb block can be configured as a single/dual-port RAM
    • Supports multiple aspect ratios, data-width conversion and parity
  • Up to 16 Mb of integrated Flash memory
    • System flexibility with up to 11Mb of on-chip user Flash
