Patent ID: 7768789

Claim:
A flash-memory drive comprising: an upper metal case made from metal; a lower metal case made from metal; a printed-circuit board assembly (PCBA) that comprises: a circuit board having wiring traces; a plurality of flash-memory chips mounted to the circuit board; a controller chip mounted to the circuit board, the controller chip having a input/output interface circuit for interfacing to an external computer, and a processing unit for accessing the plurality of flash-memory chips in response to commands from the external computer received by the input/output interface circuit; and a connector mounted to the circuit board, for connecting the controller chip to the external computer; a conductive tab that contacts the upper metal case and contacts ground traces on the circuit board, wherein the ground traces connect to a chassis ground through the connector when the connector is connected to the external computer; wherein the upper metal case is attached to the lower metal case during assembly with the PCBA between the upper metal case and the lower metal case, with the connector passing through an opening between the upper metal case and the lower metal case, the upper and lower metal cases encapsulating the circuit board, wherein the plurality of flash-memory chips are block-addressable and not randomly-addressable.
