Some DDR standards listed here are proposed or future standards not yet available.
MTps = megatransfers per second
MBps = megabytes per second
ns = nanoseconds (billionths of a second)
FPM = Fast Page Mode
EDO = extended data out
SO-DIMM = small outline dual inline memory module
DDR = double data rate
