FRAM read speed is around 50% that of DRAM. There was no mention in the article of an issue with device lifetime. RAMTRON's FRAM devices are manufactured by Fujitsu. RAMTRON has been shipping FRAM devices since 1992. > I certainly won't cry if flash goes away, but I hunch it will be a while > before MRAM becomes a serious competitor (ie. can be made cheaper than NAND). Yes, it will be a little while so we shall all be putting up with the pain of FLASH fro quite soem time to come. Gordon
