Crucial Technology has begun selling 512 MB and 1 GB microSD memory card. The cards are tinier cousins of the familiar SD card and are mainly used in cellular phones. The cards include an adapter that let users pop the card into a normal SD card slot.

Crucial is a little late to the MicroSD market and several other firms like SanDisk, PNY and Corsair already sell 512MB, 1GB and even 2GB cards.

The 1 GB and 512 MB cards sell for $31 and $20 Dollars respectively on Crucial's website.
