Toshiba will launch low-cost eMMC solutions for use in entry-level and mid-range smartphones and tablets around the end of the fourth quarter, 2013, according to sources at memory makers.

　　Targetng China's mobile device market, Toshiba is developing eMMC solutions comprising triple-level cell NAND flash memory, said the sources. The low-cost eMMC devices incorporate controller chips provided by Taiwan-based Phison Electronics, the sources added.

　　Rival Samsung Electronics is already capable of making TLC-type NAND chips for use in embedded storage devices including eMMCs and SSDs, by overcoming problems with speeds and useable life, the sources noted. The approach has allowed the vendor to efficiently adopt a competitive pricing strategy, the sources said.

　　Single-level cell (SLC) and multi-level cell (MLC) NAND flash chips have been commonly used for eMMCs due to faster transfer speeds and longer life. Nevertheless, the availability of TLC NAND chips is expected to help demand for eMMCs expand beyond high-end mobile device applications.

　　With Toshiba joining Samsung in the production of low-cost eMMCs for smartphones and tablets, the penetration rate of eMMCs in the overall mobile device market is set to rise significantly, the sources believe.
