The RAM500 memory expansion module contains a single 3.3V, 256 x 8, Serial EEPROM
device (AT24C02). The Serial EEPROM provides Serial Presence Detect (SPD) storage of the
module memory subsystem configuration. The RAM500 SPD is software addressable by a
unique address as follows: The first RAM500 attached to the host board has its SPD
addressable at $AA. The second RAM500 attached to the host board has its SPD addressable
at $AC. This dynamic address relocation of the RAM500 SPD shall be done using the bottom-
side connector signal A1_SPD and A0_SPD.
Note: DQMB1, CS_E_L, A1_SPD,CLK3,4 from Bottom
Connector is routed to Top connector
at the DQMB0, CS_C_L and A0_SPD,CLK1,2 pins.
