what is MAJOR difference bet SDRAM & DDRAM?

Answer 1

ddram only holds data for nanoseconds while the cpu gets ready to process the information. once the information is pasted on it is deleted..pretty much it just makes things faster.

sdram pretty much waits on clock ticks before repondind to istruction. it provides a way for the memory controller both to understand clock ticks and ajust themselves to the same clock.

Answer 2

DDR = Dual/Double Data Rate
SDRAM = Synchronous Dynamic RAM (in sync with CPU clock)


Short for Double Data Rate-Synchronous DRAM, a type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip's data throughput. DDR-SDRAM also consumes less power, which makes it well-suited to notebook computers. DDR-SDRAM is also called SDRAM II. and DDRAM

Answer 3

1. SDRAM is older.
2. The socket is different (no of pins and recesses)
3. The needed motherboard frequency.

Answer 4

ddr ram is double data memory which gives higher performance. and sdram is well crap.

Answer 5

speed is the major difference DDR is much faster

Answer 6

the manufaturing is also different.in DDRam s capacitors are used and SDR s transistors are used SDRs are needed frequent refreshment of charge.so they consume more poweer
