Dynamic Random Access Memory or DRAM, is most easily explained as rows and columns, or a matrix of memory cells laid out in a square. DRAM is a temporary storage bin for information that can be used to move to and from the CPU, video card and peripherals. EDO has gained quick and wide acceptance due to its easy implementation. EDO comes in a 72 pin package and for Pentium class computers modules are installed in pairs. It was developed after EDO and is quite different in that it can synchronize itself with the system CPU clock, and therefore eliminate timing delays and wait states.
Computers have to be designed to take advantage of new memory types.
It is also much more expensive than FPM or EDO memory. Hopefully I've explained enough about the different types of main memory to either identify the kind you have, or to help you make an informed decision for your next computer. We are almost always in need of good articles. If anyone has something that they feel would make a good article, an interesting story to tell, or even a good meeting topic, please don't hesitate to pass it on. Various ways are available.
