Rambus will next week unveil 'Chipkill', a method to make high-end server memory fault tolerant. According to a report in the UK's Electronics Weekly, Chipkill will allow Rambus' high-speed Direct DRAM to be used in mission-critical servers. The story doesn't reveal any details of how Rambus will add fault-tolerance to its chips -- so we're naturally keen to hear from unnamed 'sources close to the company who can fill us in -- but it's likely to involve building some level of memory cell redundancy into the chip itself -- a kind of 'RAID for RAM', if you like. It will be interesting to see how this can be achieved without drastically hitting the memory capacity a chip delivers to the host system -- unless, of course, the idea is that high-end servers have so much memory, reserving a stack of it to mirror data from the rest of the RAM bank isn't an issue. Chipkill will be integrated into the next generation of 256Mb Direct DRAM chips, said the report. ®
