Apple Diversifying Memory Suppliers Too, Moving Away from Samsung [Updated]
According to Digitimes, Apple is continuing to diversify its suppliers and moving away from its dependance on Samsung:
Apple has increased its purchases of DRAM and NAND flash from Japan, according to industry sources, adding that Toshiba and Elpida Memory are being pinpointed as beneficiaries of the increased procurement.Apple and Samsung have been in increasingly escalating legal battles over patent claims concerning Apple's iOS devices and Samsung's Galaxy line These lawsuits are said to be the reason for Apple's shifting of suppliers. Apple had previously been reported to have moved from Samsung to TSMC for production of the A6 processor in 2012. Meanwhile, Samsung has even threatened to sue Apple over the iPhone 5 once it is released.
Apple had quickly become Samsung's biggest customer with contracts for over $7.8 billion in parts in 2011. Apple seems to be doing its best to shift those contracts to Samsung's competitors over the next year.
Update: Reuters reports that Samsung has announced a $10 billion investment in a new flash memory production line, hoping to increase its share of the market and lower its own costs. Samsung will take approximately nine months to get the new line fully up and running.
