+ * There are several things to be aware of that aren't at all obvious:
+ *
+ *
+ * SOCKETS, SOCKET SETS, BANKS, ROWS, CHIP-SELECT ROWS, CHANNELS, etc..
+ *
+ * These are some of the many terms that are thrown about that don't always
+ * mean what people think they mean (Inconceivable!).  In the interest of
+ * creating a common ground for discussion, terms and their definitions
+ * will be established.
+ *
+ * Memory devices:      The individual chip on a memory stick.  These devices
+ *                      commonly output 4 and 8 bits each.  Grouping several
+ *                      of these in parallel provides 64 bits which is common
+ *                      for a memory stick.
+ *
+ * Memory Stick:        A printed circuit board that aggregates multiple
+ *                      memory devices in parallel.  This is the atomic
+ *                      memory component that is purchaseable by Joe consumer
+ *                      and loaded into a memory socket.
+ *
+ * Socket:              A physical connector on the motherboard that accepts
+ *                      a single memory stick.
+ *
+ * Channel:             Set of memory devices on a memory stick that must be
+ *                      grouped in parallel with one or more additional
+ *                      channels from other memory sticks.  This parallel
+ *                      grouping of the output from multiple channels are
+ *                      necessary for the smallest granularity of memory access.
+ *                      Some memory controllers are capable of single channel -
+ *                      which means that memory sticks can be loaded
+ *                      individually.  Other memory controllers are only
+ *                      capable of dual channel - which means that memory
+ *                      sticks must be loaded as pairs (see "socket set").
+ *
+ * Chip-select row:     All of the memory devices that are selected together.
+ *                      for a single, minimum grain of memory access.
+ *                      This selects all of the parallel memory devices across
+ *                      all of the parallel channels.  Common chip-select rows
+ *                      for single channel are 64 bits, for dual channel 128
+ *                      bits.
+ *
+ * Single-Ranked stick: A Single-ranked stick has 1 chip-select row of memory.
+ *                      Motherboards commonly drive two chip-select pins to
+ *                      a memory stick. A single-ranked stick, will occupy
+ *                      only one of those rows. The other will be unused.
+ *
+ * Double-Ranked stick: A double-ranked stick has two chip-select rows which
+ *                      access different sets of memory devices.  The two
+ *                      rows cannot be accessed concurrently.
+ *
+ * Double-sided stick:  DEPRECATED TERM, see Double-Ranked stick.
+ *                      A double-sided stick has two chip-select rows which
+ *                      access different sets of memory devices.  The two
+ *                      rows cannot be accessed concurrently.  "Double-sided"
+ *                      is irrespective of the memory devices being mounted
+ *                      on both sides of the memory stick.
+ *
+ * Socket set:          All of the memory sticks that are required for
+ *                      a single memory access or all of the memory sticks
+ *                      spanned by a chip-select row.  A single socket set
+ *                      has two chip-select rows and if double-sided sticks
+ *                      are used these will occupy those chip-select rows.
+ *
+ * Bank:                This term is avoided because it is unclear when
+ *                      needing to distinguish between chip-select rows and
+ *                      socket sets.
+ *
