Abstract:
A byte lane of an integrated circuit including two data strobe loopback paths that allow external test signals to flow in and out of the integrated circuit through data strobe pins in two opposite directions. The integrated circuit includes a Feed Forward Equalization (FFE) path configured to send FFE signals output from the FFE logic via a transmitter set to a first data strobe interface during a normal operation. In a loopback test mode operation, a test signal can be supplied from a second data strobe interface and output to the first data strobe interface by reusing the FFE path. The second loopback path conversely allows a test signal to be routed from the first data strobe interface to the second.

Claim (Index 18):
A method of performing external loopback tests on an integrated circuit, the method comprises:\n receiving a test signal at a first data strobe interface of said integrated circuit; sending said test signal to a first receiver coupled to said first data strobe interface; sending said test signal from said first receiver to an input of a first multiplexer, wherein said first multiplexer comprises: another input coupled to an output of Feed Forward Equalization (FFE) logic; and an output coupled to a first transmitter set; sending a select signal to said first multiplexer, wherein said select signal is operable to control said first multiplexer to output said test signal; and sending said test signal from said multiplexer to said first transmitter set; and sending said test signal from an output of said first transmitter set to a second data strobe interface of said integrated circuit.
