SIMM socket is only 72-pin, and is only single side. The golden finger signals on each side of PCB are identical. That is why it was
called Single In Line. SIMM is made by FPM or
EDO
DRAM and supports 32-bit data. SIMM had been phased out on current
motherboard design.

SMBus is also called I2C bus. It is a two-wire bus developed for component communication (especially for semiconductor IC). For
example, set clock of clock generator for jumper-less motherboard. The data transfer rate of SMBus is only 100Kbit/s, it allows one
host to communicate with CPU and many masters and slaves to send/receive message.

SPD is a small ROM or EEPROM device resided on the DIMM or RIMM. SPD stores memory module information such as DRAM
timing and chip parameters. SPD can be used by
BIOS
to decide best timing for this DIMM or RIMM.
