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

SDRAM is one of the DRAM technologies that allow DRAM to use the same clock as the CPU host bus
and do not have clock signal). It is similar as
3.3V. AOpen is the first company to support dual-SDRAM DIMMs onboard (AP5V), from Q1 1996
