MEMORY MAKER Lexar has announced 32GB and 64GB microSD cards for smartphones and tablets that support 45MB/s data transfer.
Lexar, part of DRAM and NAND maker Micron, announced 32GB microSDHC and 64GB microSDXC memory cards. The firm said the cards have read bandwidth of 45MB/s and come with a USB3 reader to transfer files to PCs.
Lexar's two new memory cards use Micron's 64Gbit NAND flash memory fabbed on a 20nm process node. The firm also stacks the modules and cites its own firmware tweaking as the reason why the two memory cards achieve the 45MB/s read bandwidth, though it didn't specify write bandwidth, which could be a concern for those who use smartphones and tablets to record video.
Manisha Sharma, director of product marketing at Lexar said, "Mobile devices are increasingly being used to capture all of life's important moments, and the expectation to capture high-quality video is becoming the norm, so people need a reliable and efficient way to store and manage this content."
Smartphone and tablet users should be aware that while microSDXC cards are physically capable of fitting into microSDHC slots, many devices still do not support the standard. Lexar said the 32GB and 64GB microSD cards will be available in November and carry price tags of $70 and $140, respectively. µ
