Notes to Table 1–2:
(1) This mapping is a non-socket replacement path that requires a different board design for the Stratix IV E device and the HardCopy IV E device.
(2) The Hybrid FBGA package requires additional unused board space along the edges beyond the footprint, but its footprint is compatible with
the regular FBGA package.

Memory Resources
The TriMatrix memory in HardCopy IV devices supports the same memory functions
and features as Stratix IV devices. You can configure each embedded memory block
to be a single- or dual-port RAM, FIFO, ROM, or shift register using the
MegaWizard^™ Plug-In Manager in the Quartus II software.
HardCopy IV embedded memory consists of memory logic array blocks (MLABs),
M9K, and M144K memory blocks and has a one-to-one mapping from the Stratix IV
memory. However, the number of available memory blocks differs based on density,
package, and Stratix IV FPGA-to-HardCopy IV ASIC mapping paths.
f For more information about HardCopy IV embedded memory resources, refer to the
Mapping Stratix IV Device Resources with HardCopy IV Devices chapter.
While all three memory types are dedicated resources in Stratix IV devices, only the
M9K and M144K memory blocks are dedicated resources in the HardCopy IV
devices. However, the same functionality of the Stratix IV MLABs can be supported in
HardCopy IV devices. The Quartus II software maps the Stratix IV MLAB function to
the appropriate HCell macro that preserves the memory function. This allows the
HardCopy IV core fabric to be used more efficiently, freeing up unused HCells for
adaptive logic modules (ALMs) or digital signal processing (DSP) functions.
