Memory Systems Overview
Note The NPE-300 contains two banks of SDRAM. Both SDRAM banks are used for all packet
memory requirements; however, bank 0 is used exclusively for packet memory and is set at a fixed
configuration in the factory.
Bank 1 contains two user-configurable SDRAM slots, DIMM slot 2 and DIMM slot 3 (see Figure 7).
Both slots in bank 1 can be populated by DIMMs of different sizes; however, the size of the DIMM
in slot 2 must be greater than or equal to the size of the DIMM in slot 3, and the size of the DIMM
in slot 3 can be zero.
