To improve the timing margins a PLL is used to generate external clocks, which minimize the skew
between the local bus and the memory clock.

Contrary to older DRAM technologies, SDRAM devices typically are organized either x4, x8, x16, or x32.
There are no mainstream devices that include parity support. To allow for error protection on the local bus
an additional SDRAM for the 4 parity bits must be used. Since the local bus allows for SDRAM accesses
with less than the full port size, read-modify-write cycles are supported for SDRAM write cycles.
