Altera_ForumHave a look at the cyclone II literature, on page 4 of that document (http://www.altera.com/literature/hb/cyc2/cyc2_cii51001.pdf)

The Cyclone II C35 on the DE2 has 105 M4K RAM blocks (4kbits + 512 parity bits) which add up to a total amount of 483,840 RAM bits.
Using the MegaWizard tool you can generate one or more memories with databus widths according to your needs, and as long as it does not exceed the amount of M4K RAM blocks. For a RAM with an 8bit interface you can generate a ram with 53760 words at maximum (using all M4K RAM blocks). So this corresponds to 52.5KB - Altera_Forum
oic... thanks for the explanations !
