LAS VEGAS--Lexar plans to introduce faster, higher-capacity CompactFlash cards using a new generation of the flash memory technology, a company executive said Wednesday.

Lexar's current top-end 300X-rated CompactFlash cards use a standard called UDMA (Ultra Direct Memory Access) to transfer data at 45MB/second, and their capacity tops out at 16GB. But using a new generation of the standard, UDMA 6, Lexar will release cards that have significantly faster transfer speeds and larger capacity, Jeff Cable, director of marketing, said in an interview here at the Photo Marketing Association (PMA) show here.

Cable wouldn't be pinned down on precise details, but he said the new cards' capacity "probably" would be 32GB, and their transfer speeds likely would "pretty close to" UDMA 6's threshold of 100MB/sec, which is more than double that of today's UDMA.

Only newer SLR (single lens reflex) cameras support current UDMA technology, but it's spreading, and there are benefits. For example, cameras can take longer continuous bursts of photos, and photographers can zoom faster to check focus when reviewing shots on the camera LCD. Video, which is arriving in new SLRs, also can saturate data-transfer pathways.
