Note to Figure 2–20:
(1) Device shown is an EP1S60 device. The number and position of M-RAM blocks varies in other devices.
The M-RAM block local interconnect is driven by the R4, R8, C4, C8, and
direct link interconnects from adjacent LABs. For independent M-RAM
blocks, up to 10 direct link address and control signal input connections
to the M-RAM block are possible from the left adjacent LABs for M-RAM
