IBM brain chip connections IBM researchers unveiled computer chip that emulate the way human brain process information.The microprocessor developed is claimed comes closer to ever replicating the human brain. IBM said their researchers had created basic design of the first neurosynaptic computing chip that recreated the phenomena between spiking neurons and synapses in a biological system,such as brain. Using digital silicon circuits inspired by neurobiology,the cognitive chips contain no biological element.Cognitive computers may eventually be used for understanding human behavior as well as environmental monitoring.The first two prototype chips are now undergoing testing. The two chips called 'core' have successfully demonstrated simple applications like navigation,machine vision, pattern recognition,associative memory and classification. Both are having 256 computational cores.One chip has 262,144 programmable synapses, while the other contains 65,536 learning syn

IBM Research - Zurich has announced  new type of inexpensive and reliable universal non-volatile memory, called phase change memory (PCM).Shattering records,it supposedly reads and writes 100 times faster than conventional flash - based memory with a latency of 10 microseconds, and is also several of order of magnitudes more reliable,with 10 million estimated write-cycles. Surprisingly, the technology behind phase change memory is not expensive and can be commercially used for a variety of devices requiring storage and memory,from servers to tablets.It's not going to be hitting markets very soon,with IBM stating the technology would enable 'a paradigm shift for enterprise IT and storage systems including cloud computing by 2016'. IBM's phase- change memory built using cells created from a special alloy , which can be electrically controlled into different physical states - crystalline with low resistance properties, amorphous with high resistance properties.Each allo
