Nvidia 65nm eDRAM :
TSMC recently announced that it has begun production of eDRAM (embedded DRAM) using a 65 nanometre process and Nvidia was the first company to get the part. TSMC describes 65nm eDRAM as a 10 layer copper part with low-k interconnects, while cell and macro size shrink between 45-50% compared to 90nm.
But this is not the only advantage that 65nm process brings to the table. EDRAM also features power-saving features like power-segmentation, sleep mode, on-die temperature monitoring, and equalising loads.
EDRAM is expected to be used heavily in next-generation graphics processors in desktops (given the future nature of decoupled GPUs), mobiles, handhelds, and consoles. The use of eDRAM does not stop with graphics, since high-end network switches can also efficiently use it.
Now, here is the kicker part: the reason why eDRAM was touted as the ideal solution for chips is its size – when compared to more common memory types used as cache (SRAM), eDRAM takes less than a quarter of the space for the same density. µ
