SanDisk has been showing off its latest line of flash memory cards at Cebit, announcing two new cards for multimedia phones.

As mobiles start including cameras and MP3 players, they need more storage, said a SanDisk spokesman. The new compact flash cards will provide just that, cost-effectively and in a small size, he said.

The company's new Reduced Size-MultiMediaCard, or RS-MMC, is a removable flash memory card, half the size of a standard SD card, and can be used in any MMC slot or SD card slot. The card will come in 32MB, 64MB and 128MB capacities, the company said.

Motorola has already signed up to use the cards in its new 3G phones, as it announced at the recent 3G conference in Cannes.

The small size and capacity of the RS-MMC cards "gives manufacturers more room to work with" to build new features into future phones, said the spokesman: "As manufacturers add new features, those components take up more space. Any component that can shrink in size is a bonus."

The card will be sold to device makers in volume at prices ranging from $14.50 (£7.90) for the 32MB card to $40 (£22) for the 128MB card, the company said. A price wasn't available for the 64MB. "Every mobile phone manufacturer is adding a compact flash card slot to provide storage for multimedia files," said the spokesman.

SanDisk has also created smaller versions of its Memory Stick Pro Duo cards. Previously available in 256MB and 512MB sizes, there will now be a new range from 32MB to 128MB. The new cards will provide a low-cost option for those users that don't want to buy the more expensive, high-capacity cards. They also will help phone manufacturers provide customers who buy a multimedia mobile phone with cheap storage options.

The lower capacity cards have improved write speed, which allows for real-time recording of high-resolution images and video. They also feature MagicGate security for the transfer of copyright-protected images and video. They are available worldwide immediately and volume pricing will range from $14 (£7.60) to $43 (£23.40).

Finally, the company announced that another flash memory product, the MiniSD card, is now available worldwide. Introduced at last year's Cebit, it offers flash memory from 64MB to 256MB. Previously, the cards were available only through retailers in Japan and device makers who bundled them.

SanDisk is also expanding into East Europe, with its products to be made available in Estonia, Latvia, Lithuania, Bulgaria, Slovenia, Macedonia, Serbia-Montenegro and Bosnia-Herzegovina in the next few months.
