Back 29

Refers to the groups of memory chips that a memory controller accesses.

Front 30

When the memory controller sees these two groups of memory chips separately

Back 30

Double sided RAM

Front 31

When RAM has one group of memory chips, the memory controller an access it as one group.

Faster than double sided RAM
