TriMatrix memory supports mixed-width configurations, allowing
different read and write port widths. When using mixed-width mode, the
LSB is written to or read from first. For example, take a RAM that is set up
in mixed-width mode with write data width ×8 and read data width ×2.
If a binary 00000001 is written to write dress 0, the following is read out
of the ×2 output side:
