System, method and storage medium for providing a high speed test interface to a memory subsystem

Abstract

A buffer device for testing a memory subsystem. The buffer device includes a parallel bus port adapted for connection to a slow speed bus and a serial bus port adapted for connection to a high speed bus. The high speed bus operates at a faster speed than the slow speed bus. The buffer device also includes a bus converter having a standard operating mode for converting serial packetized input data received via the serial bus port into parallel bus output data for output via the parallel bus port. The buffer device also includes an alternate operating mode for converting parallel bus input data received via the parallel bus port into serial packetized output data for output via the serial bus port. The serial packetized input data is consistent in function and timing to the serial packetized output data.
