SD-RAM is synchronous Dynamic RAM and it is the only type of RAM that can be used in a laptop.

No. SDRAM and DDR SDRAM are not compatible with each other.


PC133 is an SDRAM standard. SDRAM is a type of RAM.


Physical size of the memory card. Mobile sdram is smaller than sdram for desktops.


No. SDR SDRAM and DDR SDRAM modules are not interchangeable.


2 on desktop non DDR SDRAM and 1 on laptop SDRAM


Sdram has one notch. Depending upon the model of Sdram the number of pins it has can vary but a standard Sdram has 184 pins.


The fastest technology in actual is laan, laan is the longest and most profound memory ever.


DDR SDRAM uses 184 pins.


supplied by webopedia.com Short for Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing EDO DRAM in many newer computers. SDRAM is a variant of DRAM in which the memory speed is synchronized with the clock pulse from the CPU. This synchronization enables the SDRAM to pipeline read and write requests. Pipelining enables the SDRAM to accept commands at the same time as it is processing other commands. There are three variants of SDRAM: Single Data Rate SDRAM - SDR SDRAM Dual Data Rate SDRAM - DDR SDRAM


The term DDR SDRAM refers to the phrase "double data rate synchronous dynamic random access memory". DDR SDRAM is simply a faster version of SDRAM in which data travels at a double rate. If your computer specs say that it uses DDR SDRAM it can take DDR SDRAM, but not SDRAM. DDR is 184 pins and has a notch in the bottom near the center and you will be unable to put DDR in an SDRAM mother board and also unable to put SDRAM in a DDR motherboard. Recently a new type of RAM has been introduced to market called DDR2. DDR2 is its own type and will not fit into a DDR motherboard. Hope this helps. Peace.


SDRAM modules are available in sizes ranging from 16 MB to 1 GB.



Dram and Sdram are two different types of memory.


In order to upgrade SDRAM with DDR, you will need to replace your motherboard. DDR uses a different slot than SDRAM, so if your motherboard is using SDRAM currently, you will most likely have to replace your motherboard in order to make your system support DDR.


The actual term for computer memory SDRAM is Synchronous Dynamic Random Access Memory. You can learn more about SDRAM online at the Wikipedia website.


SDRAM is faster and better performance than EDO


DDR SDRAM has one notch and uses 184 pins.


DDR SDRAM performs 2 transfers per clock cycle



Ddr dimm has 184 Sdram dimm has 168


The main difference between Synchronous random access memory, SDRAM and Dynamic Random Access Memory, DRAM is that SDRAM is synchronous while DRAM is asynchronous. As such, SDRAM is efficient in retrieving and storing data than DRAM.


DDR2 SDRAM modules are available single sided and double sided.


Data path widths for DDR SDRAM can be at least 8, 16, 32, 64 and 72 bits, according to a DDR SDRAM contoller chip manufacturer.


No. SDRAM has two notches and DDR SDRAM has only one so besides all the electrical incompatibilities it won't physically fit.


Yes it seems that the older p4 mother boards came with the SDRAM slot. But the newer ones don't seem to come with the SDRAM slot, they have ddr slots now.
