DDR means double rate synchronous dynamic random access memory. KVR refers to the memory stick produced by Kingston. The difference between the two is as follows:
1. Different characteristics
1. DDR: DDR memory transmits data twice in one clock cycle. It can transmit data twice in the rising period and falling period of the clock. Transfer data once.
2. KVR: Kingston memory has always been the memory product with the highest shipment volume in the market. This brand of memory has good compatibility, has a very good reputation and is very cost-effective.
2. Different frequencies
1. DDR: The memory controller can use this data filtering signal to accurately locate the data, output it every 16 times, and resynchronize the data from different memory modules. data.
2. KVR: Memory capacity: 2GB? Memory frequency: 1333MHz Memory transmission type: DDRâ…¢ Transmission standard: PC3 10600.
3. Different advantages
1. DDR: DDR memory uses the SSTL2 standard that supports 2.5V voltage, instead of the 3.3V LVTTL standard used by SDRAM.
2. KVR: Kingston has obtained a patent for the single in-line memory module (SIMM) to expand memory in computer systems.
