all the DDR memorys are SDRAM, we just call them DDR

To be precise: they're DDR SDRAM (Double Data Rate Dynamic Random Access Memory) vs SDR SDRAM (Single Data Rate Synchronous etc...).

Because in DDR information in accessed on both the falling and rising edges of the clock signal.

BTW. EDO and FPM memories are also Dynamic, but in contrast to SDRAMs are Asynchronous 😉

...and dynamic ones, unlike static ones, need periodic refreshing.
