DDR2: a Soon-to-be DDR Replacement. Theoretical Basis and First Low-level Test R Review
|
Posted on Friday, June 18 2004 @ 15:52:45 CEST by LSDsmurf |
DDR2 is a new memory standard approved by JEDEC (Joint Electronic
Device Engineering Council) that comprises a great number of DIMM and
chipset manufacturers. The standard's eariler versions were published
back in March 2003, but it wasn't until January 2004 that it gained
the ultimate approval and got the name of DDR 2 SDRAM SPECIFICATION,
JESD 79-2, revision A (JESD79-2A). DDR2 is based on a well-known and
time-proved DDR (Double Data Rate) technology. We can even say that it
begins where the latter ends. In other words, first DDR2's will work
at the frequencies that are the limit for this generation of DDR-400
(PC3200 standard, 200-MHz clock frequency), while its further variants
will leave the latter even farther behind.
