A method and apparatus for increasing the amount of memory available to a host device that utilizes flash memory are disclosed. In a preferred embodiment, a flash card comprising flash memory and a transmitter for transmitting data via wireless communication is utilized within a host device. Such flash card may store data in its flash memory, and may transmit data from the flash card to an extended storage device via wireless communication. In a preferred embodiment, such wireless communication is radio frequency (RF). Data transfer from the flash card to an extended storage device may be initiated by a mechanism on the flash card or on the host device. In a preferred embodiment, the flash card further comprises a receiver for receiving wireless signals. In such an embodiment, an extended storage device may initiate a data transfer by transmitting the appropriate signals to the flash card. In a preferred embodiment, an extended storage device may comprise a transmitter for further transmitting the data to another storage device(s). Such transmitter may be a more powerful transmitter than provided in the flash card, such that the extended storage device may transmit data to a more remote location. Advantageously, in a preferred embodiment an extended storage device may be a less expensive form of storage than flash memory.
