MMC Cards

Delkin Devices’ MMCplus card is relative to the size of a postage stamp, and is as thick as a credit card. This solid state storage solution features low power consumption and high data throughput. MMCplus and MMCmobile are based on Single Level Cell (SLC) NAND Flash. NAND Flash is non-volatile and retains the data without the need of a continuous power source.
