1. A portable data storage device comprising:
- a non-volatile memory; and
a wireless data interface coupled to said non-volatile memory to read data from said non-volatile memory for transmission through said wireless data interface and/or write data received from said wireless data interface to said non-volatile memory,wherein said wireless data interface is a high data rate interface configured to transmit and/or receive data at a data rate of at least 100 Mbps;
wherein the portable data storage device further comprises;
a control unit configured to control said wireless data interface to operate in a sleep mode, and wherein the control unit is configured to determine, in the sleep mode, whether data is received by the high data rate interface which indicates a request for memory access, wherein said request is indicated by using a pre-defined data pattern at a pre-defined frequency.

Abstract
A portable data storage device is provided having a non-volatile memory and a wireless data interface. The wireless data interface is coupled to the non-volatile memory to read data from the non-volatile memory for transmission through the wireless data interface and/or write data received from the wireless data interface to the non-volatile memory. The wireless data interface is a high data rate interface and/or a broadband interface. Data rates may be above 100 Mbps, and bandwidths may be 100 MHz or above. There is further provided a corresponding data storage method.

37. A method of storing data, comprising:
-
transmitting data to be stored to a portable data storage device through a wireless link at a high data rate and/or in an ultra wide band; receiving said data at the portable data storage device; and storing the received data in a non-volatile memory of the portable data storage device; wherein the method further comprises; a control unit of said portable data storage device causing the portable data storage device to operate in a sleep mode; determining, while operating in the sleep mode, whether data is received by the wireless link that indicates a request for memory access, wherein said request is indicated by using a pre-defined data pattern at a pre-defined frequency. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
