Which type of memory transfers data twice as fast as SDRAM and increases performance by transferring data twice per cycle?
- A.
DDR-SDRAM
- B.
DRAM2
- C.
D-SDRAM
- D.
ROM
Correct Answer
A. DDR-SDRAMExplanation
DDR-SDRAM stands for Double Data Rate Synchronous Dynamic Random Access Memory. It is a type of memory that transfers data twice as fast as SDRAM (Synchronous Dynamic Random Access Memory). DDR-SDRAM increases performance by transferring data twice per cycle, which means it can transfer data on both the rising and falling edges of the clock signal. This allows for higher data transfer rates and improved overall system performance.Rate this question:
