The XVME-956/101 Memory Expansion Module (MEM) is an embedded system module which
provides a convenient means to expand your Xycom VME AT system. I n addition, with the use of the
XVME-971 MS-DOS Solid State Disk software package, the XVME-956/101 allows replacement of
mechanical disk drives for use in embedded systems.* The XVME-956/101 MEM four byte-wide
memory sockets are organized into two groups of two sockets each. Each group can be configured for
a different type of memory device, allowing many possible memory configurations. A l l of the 32 to
512 Kbyte static RAMs, as well as many types of Flash EPROMs are supported.
