Samsung Electronics said on Wednesday it has developed a tiny, 2G-byte memory card for use in mobile phones, just three months after it announced a card with half of that capacity.
The 2G-byte MMCmicro card is about the size and shape of one key on a standard computer keyboard and just 1.1 millimeters (0.04 inches) thick. It can store as much as 12 hours of "mobile video," Samsung said, without specifying a format.
It can also transmit data quickly. A user can download three hours of mobile video, for example, in less than two minutes, according to Samsung. The cards can read data at 10M bps (bits per second) and write at 7M bps, the Seoul-based company said.
Both the 2G-byte and 1G-byte cards are expected to become available later this year, Samsung said. There was no word yet on pricing.
The cards are based on MMCmicro, a format designed by Samsung that's based on the MMC (Multimedia Card) standard. The MMC standard competes with SD (Secure Digital) cards. Many handset makers, including Samsung, make phones compatible with both card types.
Earlier this year, SanDisk Inc. announced a 1G-byte card based on its smallest memory card format, MicroSD.
Memory card developers are reducing the size of the cards and boosting their memory capabilities to accommodate for small cell phones and for the additional data services that cellular operators are offering.
