Abstract
Methods and systems for storing and accessing data in UAS based flash memory device are disclosed. UAS based flash memory device comprises a controller and a plurality of non-volatile memories (e.g., flash memory) it controls. Controller is configured for connecting to a UAS host via a physical layer (e.g., plug and wire based on USB 3.0) and for conducting data transfer operations via two sets of logical pipes. Controller further comprises a random-access-memory (RAM) buffer configured for enabling parallel and duplex data transfer operations through the sets of logical pipes. In addition, a Smart Storage Switch configured for connecting multiple non-volatile memory devices is included in the controller. Finally, a security module/engine/unit is provided for data security via user authentication data encryption/decryption of the device. Furthermore, the flash memory device includes an optical transceiver configured for optical connection to a host also configured with an optical transceiver.
