Some xSeries servers support 4-way memory interleaving and some support 2-way interleaving. In both types of interleaving， the data is accessed 256 bits at a time. How is this 256-bit data access achieved with 2-way interleaving？（）
A
The DIMMs used for 2-way interleaving are double the width of DIMM used in 4-way interleaving.
B
The DIMMs used for 2-way interleaving are 64-bit wide and data bits are accessed both on the rising edge and falling edge of the clock cycle.
C
The DIMMs used for 2-way interleaving are 32-bit wide and data bits are accessed both on the rising edge and falling edge of the clock cycle.
D
The DIMMs used for 2-way interleaving are double the width and data bits are accessed both on the rising edge and falling edge of the clock cycle.
