Which memory types use 240 pins?

DDR2 and DDR3
DDR and DDR2
SDRAM and DDR
DDR3 and DDR4

The correct answer is: DDR2 and DDR3

DDR2 and DDR3 memory types use 240 pins, while DDR, SDRAM, and DDR4 use a different amount of pins. DDR and DDR2 use 184 pins, while SDRAM uses 168 pins and DDR4 uses 288 pins. This is due to the different layouts and designs of each memory type, with higher generation DDR versions typically requiring more pins for faster data transfer speeds. Therefore, A is the correct answer as it is the only combination of memory types that use 240 pins.
