TOKYO--Toshiba Corporation, a leading innovator in memory card solutions, today expanded its line of small-format, high-speed, high-capacity memory cards with the announcement of the launch of a 4-gigabyte (GB) microSDHC card. The addition of the new card extends Toshiba's comprehensive range of microSDHC cards, the preferred memory card for mobile phone applications, from 256MB up to 4GB. The new cards will be available worldwide from July.

Toshiba's 4GB microSDHC card meets SD memory card standard Ver. 2.00, the SD card standard for high density SD products with a capacity of over 2GB. The card is designed for use in dedicated microSDHC slots, but can also be used in standard SDHC card slots in an adapter.
