SanDisk, Motorola Shrink Memory Cards

SanDisk and Motorola have created a smaller removable flash memory card format for use in mobile phones. The first cards will go on sale in the third quarter to coincide with the launch of a 3G Motorola phone designed to use them, says Kelly Radmer, 3G marketing manager at Motorola.

Motorola showed 32MB versions of the card on its stand at the 3GSM World Congress in Cannes, France, and the cards will eventually be available in capacities up to 512MB, Ms. Radmer says.

Earlier this week, Motorola announced details of two 3G phones, the E1000 and A1000, that will use the cards. The E1000, using Motorola's own Synergy operating system, will go on sale in the third quarter, and in the fourth quarter the A1000 will appear, running an operating system (OS) from Symbian.

Two other phones announced that day, the MPx and MPx-100, accept SD cards and miniSD cards, respectively, but future Motorola phones containing memory cards will all use the new format, Ms. Radmer says.

At approx. 5 x 4 in in size, the new cards are said to be smaller than the miniSD card, announced less than a year ago. By comparison, miniSD cards measure 8 x 7 in, and weigh about 0.04 oz.

Memory cards have been getting smaller in size and larger in capacity throughout the years, but the progress is still not great enough. The new card format is important for phone manufacturers such as Motorola because, as phones get smaller, even miniSD card connectors take up too great a proportion of the phone's volume, Ms. Radmer says.

The memory card specification will be made available to other manufacturers, Ms. Radmer says. "It's open to everyone," she says.

SanDisk Spokesman Bob Goligoski confirms the company's involvement with Motorola in developing the cards. SanDisk is expected to provide further details at an official launch event planned for March 9 in Redwood City, CA, U.S.

Pricing has not yet been decided, he says, and although no final decision has been taken on a name for the cards, they will not carry the name Motorola representatives in Cannes are using for them, TriFlash-R. SanDisk uses the TriFlash name for a memory chip technology it introduced in 2000, electrically compatible with cards based on the SD, miniSD, and MMC specifications.

No details of the performance of the cards, or their electrical characteristics, were available from either party. However, the presence of the adapter, and the coincidence of the TriFlash name, suggests they could be compatible with either SD or MMC cards, some memory card experts suggest.

When contacted, representatives of the SD Card Association in the U.S. and Japan say they have not heard of the new card format.

Sony Ericsson Mobile Communications, which also plans a news conference about multimedia mobile phone accessories on March 9, is not involved in the memory card project, according to Mr. Goligoski. (IDG News Service)
