FLEX 10KE Embedded Programmable Logic Devices Data Sheet

When used as RAM, each EAB can be configured in any of the following

sizes: 256 × 16, 512 × 8, 1,024 × 4, or 2,048 × 2 (see Figure 5).

Larger blocks of RAM are created by combining multiple EABs. For

example, two 256 × 16 RAM blocks can be combined to form a 256 × 32

block; two 512 × 8 RAM blocks can be combined to form a 512 × 16 block

(see Figure 6).

If necessary, all EABs in a device can be cascaded to form a single RAM

block. EABs can be cascaded to form RAM blocks of up to 2,048 words

without impacting timing. The Altera software automatically combines

EABs to meet a designer’s RAM specifications.
