Memory interleaving is a technique that divides main memory into several blocks (WAYs) and accesses each WAY
independently and in parallel to enable effective access to the contiguous area.
The size of one WAY is 64 bytes, which is the line size of cache memory.
SPARC® ENTERPRISE M4000 / M5000 perform memory interleaving in Group units as standard. The number of
WAYs in each configuration is as follows.
Uni-XSB configuration (16 DIMMs of memory are mounted in Groups A and B)
Uni-XSB configuration (8 DIMMs of memory are mounted in Groups A and B)
Quad-XSB configuration
