RAM names

[GRiMMi]

Well I want some confusion of mine cleared up.
Some call it DDR RAM, some call it DDR SDRAM,
Some call it SDR RAM, some call it SDRAM.

DDR = Double data rate
SDR = Single data rate

SDR RAM = Single data rate random access memory
DDR RAM = Double data rate random access memory
SDRAM = ?
DDRAM = ?
DDR SDRAM = ? (wtf ? lol)

Pls fill in the blanks, correct the wrongs, and explain this to me :)

SDRAM = Syncronous Dynamic Random Access Memory
It's the same as SDR RAM.

DDR SDRAM = Double Data Rate Syncronous Dynamic Random Access Memory
Same as DDR Ram.

DDRAM = ?
Never heard that one, but it's the same as DDR.
