Hi all; The complete list of OKI memories covered by the big new agreement:

OKI Synchronous DRAM

Size Part# Type
8Mb MSM54V25632A SGRAM 256Kx32 (obsolete)
16Mb MS82V16520 SGRAM 512Kx32 (about to be obsolete)
16Mb MSM56V16160F SDRAM 1Mx16 (about to be obsolete)
16Mb MSM56V16800E SDRAM 2Mx8 (about to be obsolete)


They appear to make no DDR or RDRAM, so it is unlikely that Rambus will see lots of royalties on those products. They did use to make concurrent RDRAM, but that is now obsolete:
okisemi.com

OKI's only Synchronous DRAM is of size 16Mb or smaller. According to Micron, 16Mb is a size that is no soon to be obsoleted (note that it is crossed out):
micron.com

To put this in proper perspective, lets take a look at what Samsung offers in the way of SGRAM and SDRAM (in "mass production", not including engineering samples or development):

Samsung Synchronous DRAM

SDRAM:
16Mb 2 types
64Mb 7 types
128Mb 6 types
256Mb 3 types

SGRAM/GSDRAM:
16Mb 1 type
32Mb 1 type
64Mb 2 types

DDR SGRAM:
64Mb 1 type


OKI's largest SDRAM is 1/16th the size of the leading parts from Samsung (or Micron). The OKI parts are verging on obsolescence, and Rambus can't rely on them for much in the way of future royalties. It is well known that OKI is exiting the commodity business (and it shows in their above product list). See, for instance, this link:

Oki has phased out commodity DRAMs,and its memory business is now centered on application-specific memories for datacom and telecom systems applications.

In other words, this agreement is even more lame than the Hitachi one. Rambus better have a real agreement with a real memory maker up its sleeve somewhere.

P.S. For a technogeek laugh, go to this .pdf from Micron and look at the listings under the "Specialty DRAM" and "RDRAM" headings. Oops, Micron screwed them up:
micron.com

Also, OKI still makes VRAM. These are the worst memory in the world to have to use, check out there data sheet. This may be the last website in the world to carry these obsolete parts:
