this IS VERY INTERESTING :=

".......KOREAN DRAM GIANT Samsung will announce today
it has created a 512Mbit DDR-II memory chip, conforming
with the JEDEC DDR-II standard set in March.
And IBM has developed a DDR-II memory interface chip,
meaning the high speed platform is almost ready to
roll.

The memory chip can transfer data at 533Mbps, claimed
Samsung, but that can be extended to 666Mbps for
special environments and for networks, the company
said.

The chip uses a 60 ball grid array package, and
includes off chip driver calibration, on die
termination and posted CAS for better bus efficiency.

The firm will say that products will go into volume in
the third quarter of 2003*.........."

Third quarter of 2003.....a YEAR from now.....sigh...

I wonder what they mean by "Special" environments?
Hmm...

The night was black was no use holding back
Cos I just had to see was someone watching me?
In the mist dark figures move and twist
was all this for real or some kind of hell?
666 megahertz RAM of The Beast
Hell and fire was spawned to be released!

Torches blazed and sacred chants were praised
as they start to cry hands held to the sky
In the night the fires burning bright
the ritual has begun Satan's work is done
666 megahertz RAM of The Beast
Sacrifice is going on tonight!

This can't go on I must inform the law
Can this still be real or some crazy dream?
but I feel drawn towards the evil chanting hordes
they seem to mesmerize me...can't avoid their eyes!
666 megahertz RAM of The Beast
666 the one for you and me!

Environments where they don't have to worry about really long trace lengths and
socketed memory modules.
eg, high end routers/switches, videocards... etc.

When you have the ram in a socket, you have to back off the timings/clockrate
somewhat.

522Mbps?? Thats slow, thats rougly 52MB/sec.
I hope they mean 522MB/s :)

by **Andreas Nystro** » Fri, 31 May 2002 00:36:21

or do they mean per chip?, then reading from chips parallel would mean
faster tranferrates i guess.

I imagine that it's 522Mbps/per pin

Per _lead_. Most MoBo:s have 64bit wide mem buses.

so: 64x533/8 ~= 4,3 GB/s

That's still slow... :)

ok. I'll up that and hope they meant 522Mhz. that'd mean 8.6GB/s,
and put us in business. :)

DDR2 is called QDR memory. It stands for Quad Data Rate.
There is many memory technologies coming out and you don't EVER have to fear
that there won't be memory fast enough
as there is memory that can clock out at the rate of gigabits per second
when referring to bitwide devices which are
what memory cells are composed of. Also, instead of going one direction,
there has been a recent pull to go into another
direction where each memory cell (since each memory cell is simply a single
transistor and capacitor) stores a non bit value.
In other words, each cell is shifted out into what you call an analog
register (a simple 4096 wide row of sample and holds
which are then clocked out to a ADC converter rated into the Ghz range. THis
allows storage which pushed technology to the
envelope, giving you Ghz access speeds, using 1/8th the actual silicon and
complexity while getting 8x speed output.
Also, there is the common VRAM which was originally made by Texas
instruments which stands for Video RAM.
It can clock out memory much, much faster than our little syncronous memory.
Then there is the non RAS/CAS memory which is
a DRAM which doesn't use RAS/MUX/CAS signals, but instead completely
eliminates multiplexing over its lines and true Random
Acess (instead of Syncronous address access) at raes into speeds exceeding
1Gigabits per second per cell. The only problem
is these devices are made with GalleniumArsenide which is very heat
sensitive and does not like extremely small devices as it
crumbles and developes microcracks much easier than typical metal oxide
doped silicon or newer, much advanced technologies.
Also, IBM is using tunneling transistors which use on the order of anywhere
between one to four atoms to make a tiny storage
cell for extremely low signals. The atoms are not directly accessed, they
are accessed through an inductive format, kind of like
old donut core memory except on the atomic level.

oh, aha! ok. I looked a bit at Samsung's websites and got the
impression they weren't the same.

bah. nothing can ever be fast enough. :)

thanks for clearing it up, "me", whoever you are. :)

Wait until we go to *photonics* using photons(light) for carrying signals
instead of *electronics* where we use electrons. Warp 10 years ahead please!
