Rambus is a memory technology that uses large burst mode data transfer. Theoretically, the
data transfer should be high than
SDRAM
. RDRAM is cascaded in channel operation. For Intel
820, only one RDRAM channel is supported, 16-bit data per channel, and this channel may have
maximum 32 RDRAM devices, no matter how many RIMM
sockets.

SDRAM is one of the DRAM technologies that allow DRAM to use the same clock as the CPU
host bus (
EDO
and FPM are asynchronous and do not have clock signal). It is similar as
PBSRAM
to use burst mode transfer. SDRAM comes in 64-bit 168-pin DIMM and operates at
3.3V. AOpen is the first company to support dual-SDRAM DIMMs onboard (AP5V), from Q1 1996
