Serial Presence Detect question..



Jan 1, 1970
Hi, I'm interfacing a microcontroller to the Serial Presence Detect
(SPD) lines on a 144-pin SO-DIMM of PC133 RAM. I understand it uses I2C
and it's just an EEPROM, and I have the read commands all setup, but
what I can't seem to figure out is how to find the device address. The
EEPROM is the only thing on the i2c bus (aside from the microcontroller
of course). I've never used i2c before, so forgive me if this is a very
obvious question. Thanks!
