Onboard DRAM

The MVME177 onboard DRAM is located on a mezzanine board. The mezzanine boards use error checking and correction (ECC) protection to correct single-bit errors and detect double-bit errors. Interrupts or bus exception can be enabled when a bit error is detected. The interrupt output from the memory mezzanine is connected to the VMEchip2 PEIRQ* interrupt input.

Mezzanine board sizes are:
