IBM and its chip development partners, including AMD, made a stunning announcement today, apparently beating Intel_Corporation in the successful production of the first functional 22_nanometer SRAM cell. 22 nm processors are still three years out in the future, but IBM’s news is a good sign that chip manufacturer will be able to easily scale to this new level by the end of 2011. It appears that, for the first time in several decades, Intel may have to put some extra time into its research and development efforts to make sure it can keep its manufacturing lead at 22 nm and beyond. SRAM chips are typically the first semiconductor devices to test a new manufacturing process as a precursor to actual microprocessors. The devices developed and manufactured by AMD, Freescale_Semiconductor , IBM STMicroelectronics, Toshiba and the College of Nanoscale Science and Engineering (CNSE) were built in a traditional six-Transistor design on a 300 mm wafer and had a memory cell size of just 0.1 μm2, which compares to Intel’s 45 nm SRAM cell size (the test chip that was used for today’s 45_nanometer processors) of 0.346 μm2.
