CPU NEWS: AMD licenses new Z-RAM technology
According to EE Times, second-gen Z-RAM is expected to allow chips to store 5Mb (625KB) of data per square millimeter on a 65nm process. Using this technology, a 65nm processor could theoretically pack 10MB of cache in an area of just 16mm2.
For reference, 65nm Intel Core 2 Duo chips have a die area of 143mm2, and going by Intel's die shots, around a third of that area is required to store 4MB of cache. Z-RAM's speed and power consumption are quite enticing, too. The second-gen tech clocks up to 400MHz and can draw as little as 10lW (0.00001W) per MHz.
