Welcome to a laptop battery specialist

Computers that don't lose their data, even when the power supply fails; laptops with batteries such as IBM 02K6928 Battery, IBM 02K6620 Battery, IBM 02K7039 Battery, IBM ThinkPad X60 Battery, IBM FRU 92P1167 Battery, IBM ThinkPad Z60t Battery, IBM ThinkPad Z61t Battery, IBM 40Y6793 Battery, IBM FRU 92P1125 Battery, IBM FRU 92P1121 Battery that supply power for days without the need for recharging; handheld computers and cell phones with huge amounts of memory; and personal computers that, at the touch of a button, pick up again at the exact spot where you left off the day before - In just a few years, this vision of the future of computing could become reality.
The fundamentals for it are offered by new types of memory technologies. Supporting this prerequisite, the German semiconductor manufacturer Infineon together with IBM have presented the world's first 16-Mbit Magneto-resistive RAM (MRAM) prototype.
MRAM chips, unlike conventional chips, use magnetization to store information, instead of electrical charges. Until now, computers had to continuously supply the main memory chips with power in order to store data. The information on MRAM memories, however, remains intact even after the system has been powered down.
The working concept is similar to the way that data is stored on a computer's hard disk drive. Infineon's 16-Mbit MRAM chip is approximately 1,000 times faster than the non-volatile flash memory used in USB sticks, handheld computers and digital cameras. This speed enables exceptionally rapid access to data.
Furthermore, information can be stored in an MRAM memory cell up to one million times more often than is possible with flash memory. The high storage capacity of the 16Mbit Chip (16 million single cells) was enabled using a small 1.4 square microns cell. By comparison 5,000 storage cells would fit on a cross section of a human hair.
"The announcement of the world's first 16-megabit MRAM memory prototype," emphasized Dr. Wilhelm Beinvogl, Chief Technology Officer for the Memory Products Business Group at Infineon Technologies, "is a significant breakthrough in the development of this new technology."
Users would profit from the elimination of the annoying boot-up phase during which current computers load data from the hard disk drive to main memory. Additional advantages would be greater convenience, since the computer retains the current state of work, and, above all, longer battery run-times in mobile devices - from laptops to cell phones -, since non-volatility enables MRAM chips to consume less power than conventional DRAM does.
Infineon has been developing the MRAM chips in cooperation with IBM since the year 2000. Infineon Technologies AG, Munich, Germany, offers semiconductor and system solutions for the automotive and industrial sectors, for applications in the wired communications markets, secure mobile solutions as well as memory products.
