The Arria® 10 devices contain two types of memory blocks:

  • 20 Kb M20K blocks—blocks of dedicated memory resources. The M20K blocks are ideal for larger memory arrays while still providing a large number of independent ports.
  • 640 bit memory logic array blocks (MLABs)—enhanced memory blocks that are configured from dual-purpose logic array blocks (LABs). The MLABs are ideal for wide and shallow memory arrays. The MLABs are optimized for implementation of shift registers for digital signal processing (DSP) applications, wide and shallow FIFO buffers, and filter delay lines. Each MLAB is made up of ten adaptive logic modules (ALMs). In the Arria® 10 devices, you can configure these ALMs as ten 32 x 2 blocks, giving you one 32 x 20 simple dual-port SRAM block per MLAB.

Embedded memory is susceptible to SEU, Intel implement interleaving and special layout techniques to minimize the FIT rate, and added Error Correction Code (ECC) feature to reduce SEU FIT rate to close to zero.
