[More ARM fabrication problems. The crisis continues...]
Toshiba Corp. has cancelled plans to sell computers that run the Windows RT operating system from Microsoft Corp. and that are based on an ARM-based processor, due to delays in getting adequate supplies of components, according to reports.
Toshiba was planning to use OMAP processors form Texas Instruments Inc. (Dallas, Texas) in the design and in June TI had produced a video showing off Windows RT running on a Toshiba tablet.
Because of poor chip supply Toshiba will now focus on making machines running the alternative Microsoft operating system called Windows 8, which runs only on x86 processors, which come from Intel Corp. and Advanced Micro Devices Inc.
Toshiba did not say which components are in so short supply as to force the cancelling of its Windows RT product, but many leading chip companies are either fabless, or have gone fab-lite, meaning that they are all dependent on foundries for their leading-edge 28-nm silicon. In particular, most are dependent on the leading foundry Taiwan Semiconductor Manufacturing Co. Ltd. (Hsinchu, Taiwan). There has been much discussion of low yields and shortages of supply of 28-nm silicon during this year.
