DRAM? SDRAM ?
Memory FAQ Topics
|DRAM? SDRAM ?|
||Can you tell by looking at a module if it is SDRAM, FPM, EDO etc?
||SDRAM, EDO and FPM chips look similar to each other. The best way to tell the difference is to reference the part number on the chip. Most DRAM manufacturers have reference books or lists on their web sites. By looking at a memory module one can attempt to guess what it is. A general guideline is to look at the IC type and size. The EDO and FPM chips are typically packaged in SOJ form and are thicker when compared to that of the SDRAM chips which are typically packaged in slim-line TSOP form. The EDO/FPM chips typically have a marking of -60 at the end of the string of numbers and that of the SDRAM chips typically have markings of -12 -10 -8 -7.5. A SDRAM module typically has a row of the resistor or resistor arrays above the contact tabs.
