TriMatrix memory has three different sizes of memory blocks, each
optimized for a different purpose or application. M512 blocks consist of
512 bits plus parity (576 bits), M4K blocks consist of 4K bits plus parity
(4,608 bits), and M-RAM blocks consist of 512K bits plus parity
(589,824 bits). This new structure differs from APEX II and APEX 20K
devices, which feature uniformly sized embedded system blocks (ESBs)
either 4 Kbits (APEX II devices) or 2 Kbits (APEX 20K devices) large.
Stratix and Stratix GX TriMatrix memory blocks give you advanced
control of each memory block, with features such as byte enables, parity
bit storage, and shift-register mode, as well as mixed-port width support
and true dual-port mode operation.
