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 Arria V devices contain two types of memory blocks:
• 20 Kb M20K or 10 Kb M10K blocks—blocks of dedicated memory resources. The M20K and M10K
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 shallow FIFO buffers, and filter delay lines. Each MLAB is made up of ten adaptive logic modules
(ALMs). In the Arria V 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. You can also configure these ALMs, in Arria V GZ devices, as
ten 64 x 1 blocks, giving you one 64 x 10 simple dual-port SRAM block per MLAB.
