Embedded Memory Blocks
The embedded memory blocks in the devices are flexible and designed to provide an
optimal amount of small- and large-sized memory arrays to fit your design
requirements.

Types of Embedded Memory
The Intel 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 Intel 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.
