Smaller density cards to enable larger drives.
Based on a report out of Japan, Toshiba, the world’s second largest flash memory producer, will be vying for the number one spot by moving towards and even smaller process technology in the coming years with investment starting this year.
The company will invest a whopping 15-billion Yen (approx $160m) into “a test production line for advanced flash memory chips” during 2010. Toshiba currently produces 32nm and 43nm memory chips, but they will soon begin production on “sub-25nm” chips that will enable chips to hold more memory onto designs that are of the same size as what we have today. This is possible because a sub-25nm will be able to store more memory onto an SDHC card because of the decrease in density.
According to the report, Toshiba could output NAND chips with circuitry widths in the upper 20 nanometre, while production of chips with widths of lower 20 nanometres is planned to set off by 2012. A spokesperson for the company also said that Toshiba plans to begin commercial production of NAND flash chips with “circuitry widths somewhere between 20 and 29 nanometres in the second half of 2010, but it has not been decided whether the circuitry will be wider or narrower than 25 nanometres.”
