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