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 Cyclone V devices contain two types of memory blocks:
• 10 Kb M10K blocks—blocks of dedicated memory resources. The 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 Cyclone 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.
