Portable object based storage device with mass storage class access

摘要

A portable device stores data objects 300 in a solid state memory along with object based organisation metadata 302. The device contains a processor which allows the data to be accessed by a host system using a mass storage class protocol. The metadata may include file allocation table data 304 which may include logical cluster data and which may be used by the processor to create a virtual file allocation table and a virtual directory table. The virtual file allocation table and virtual directory may be returned to a host system on request. The data objects may be compatible with the Media Transfer Protocol (MTP). The device may communicate using the Universal Serial Bus (USB). The memory may be non-volatile NAND flash memory.
