Using SDRAM/SRAM/Flash

Figure 3.16 shows the schematic of SDRAM, SRAM, and Flash Memory. The

DE2 Board provides 8Mbyte SDRAM, 512KByte SRAM, and 1Mbyte Flash

Memory. Figure 3.17 shows the schematic of the SDRAM/SRAM/Flash blocks.

The pin assignments of the SDRAM, SRAM, and Flash are listed in Table 3.15,

3.16, and 3.17, respectively.
