2.3 System DRAM

The Tegra 200 Series Developer Board has 8 DDR2 128M x 8 devices for 1GB total system DRAM. The DDR2 will operate up to 333MHz for a peak bandwidth of 2.7GB/s. The memory is arranged as one or two 32-bit Ranks. Each Rank uses a different Chip Select and Clock Enable. For low power operation with memory retention, self refresh is supported.

2.4 Boot Device

A 4Gb (512MB) Hynix HY27UF084G2BTPCB 8-bit NAND is available for use as the boot device. In addition, an internal 4-bit SD, 8-bit MMC socket (J26) is provided to support other flash memories.
