6 GHz SRAM Memory Introduced By IBM

post #1 of 26
Thread Starter 

Quote:
A new state of the art SRAM chipset is responsible for this achievement. The 6 GHz speed is almost twice the speed of today's SRAMs. SRAM's usage is to hold frequently accessed data used by the processor. The faster the access, the faster the data transfer from SRAM to CPU.

Its been a long time effort for researchers to be able to overcome the process variability, especially variations that occur when a device is used in conjunction with other devices in an array making it possible for data to be lost. IBM researchers have come up with a novel hardware-based solution in order to reduce or even correct all problems problems and improve performance for various applications by using 8T SRAM arrays.

Maybe off topic, but what would the speed of L2 cache be? Is there even a speed, somebody teach me.

What about L1?

Nice.

But whatever could they mean by almost twice the speed of current available SRAM?

(BTW - Anyone heard of RAM on GPU's being OC'd anywhere close to GHZ?)

Unless they mean.. PERFORMANCE wise.. and not just actual MHZ. But even so, if its as effective in ratio to current SRAM, then 6GHZ should make it FAR faster..
not just 2 times as...

Perhaps I'm thiking of something else

Isn't L1 your FSB? Not sure though.

Anyone heard of RAM on GPU's being 3 GHZ?

Unless they mean.. PERFORMANCE wise.. and not just actual MHZ. But even so, if its as effective in ratio to current SRAM, then 6GHZ should make it FAR faster..

Yup, you are thinking of something else. GPU's and main memory are DRAM. DRAM needs to be refreshed constantly. This is SRAM which doesn't need to be refreshed.

Not even close. One is memory and the other is a bus.

L1 is crap fast, L2 runs the same speed as your CPU IIRC..

Unless it's L1 that runs the same speed as your CPU and L2 is slower.. hmm

oh, guess I got them confused. The FSB is the speed of L2 , and the CPU speed is the L1 speed?

No.... cache speed and FSB have nothing to do with each other. Main memory RAM and FSB are related.

L1 is super fast/expensive memory. L2 is very fast memory. Both are intergrated into the CPU. Then there is main memory or "RAM".
