M-RAM Block
The largest TriMatrix memory block, the M-RAM block, is useful for
applications where a large volume of data must be stored on-chip. Each
block contains 589,824 RAM bits (including parity bits). The M-RAM
block can be configured in the following modes:
■
■
■
■
You cannot use an initialization file to initialize the contents of an M-RAM
block. All M-RAM block contents power up to an undefined value. Only
synchronous operation is supported in the M-RAM block, so all inputs
are registered. Output registers can be bypassed.
