The LAB of the Arria II device has a derivative called memory LAB (MLAB), which
adds look-up table (LUT)-based SRAM capability to the LAB. The MLAB supports a
maximum of 640 bits of simple dual-port SRAM. You can configure each ALM in an
MLAB as either a 64 × 1 or 32 × 2 block, resulting in a configuration of 64 × 10 or
32 × 20 simple dual-port SRAM blocks. MLAB and LAB blocks always coexist as pairs
in Arria II devices. MLAB is a superset of the LAB and includes all LAB features.
