Why does the DDR3 Micron MT41J64M16LA memory preset specify the incorrect data width?

Description

When you select the Micron MT41J64M16LA-15E memory preset in the DDR3 ALTMEMPHY based controller, the data width is incorrectly specified as 8 bits by default, but in fact, this device is a 16 bit wide device.

Resolution

You will need to manually change the data width from 8 bits to 16 bits.

This issue is fixed in the Quartus® II software version 12.0.
