A solid-state memory storage device and method for using the device includes storing data wirelessly transmitted from a host and wirelessly transmitting the data to the host. The storage device has an RF module which demodulates an ultra-wideband write signal received wirelessly from a host and outputs a wireless protocol write signal. A wireless protocol controller has a protocol conversion layer which converts the wireless protocol write signal into a USB protocol write signal. A microcontroller has function extraction layer for extracting a write command from the USB protocol write signal and, in response to the write command, controls the writing of data extracted from the USB protocol write signal to the solid-state memory to store the data in the solid-state memory. The microcontroller also reads the data stored in the solid-state memory in response to a read command received from the host and outputs a USB protocol read signal to the wireless protocol controller. The protocol conversion layer also translates the USB protocol read signal into a wireless protocol read signal. The RF module also modulates the wireless protocol read signal and outputs an ultra-wideband signal for wireless transmission to the host.
