Abstract

A system and method for providing a configurable command sequence for a memory interface device (MID). The system includes a MID intended for use in a cascade interconnect system and in communication with one or more memory devices. The MID includes a first connection to a high speed bus operating at a first data rate, a second connection to the high speed bus, an alternate communication means and logic. The first connection to the high speed bus includes receiver circuitry operating at the first data rate. The alternate communication means operates at a second data rate that is slower than the first data rate. The logic facilitates receiving commands via the first connection from the high speed bus operating at the first data rate and using a first command sequence. The logic also facilitates receiving the commands via the alternate communication means using a second command sequence which differs from the first command sequence in the speed in which the commands are transferred. The logic further facilitates processing the commands if the commands are directed to the MID and redriving the commands via the second connection onto the high speed bus.
