Ram Type

What is the difference btween EDO Ram and Fast Page Mode ? Can they be used together
in the same machine ? I have a PowerTower Pro 225 and A PowerCenter Pro 210. The Tower machine supports interleaving. I want to take some of the Ram out of the 210
and install in the Tower so as to interleave the ram. Can I do this ?

I just found a slightly simpler definition which may also be insightful. And yes, they will work together in the same machine.

FPM
Fast Page Mode (FPM) is an older technology category of DRAMs. FPM DRAMs have the ability to work within a page. A page is described as the section of memory available within a row address. Within one specific row are several columns of memory bits. With FPM DRAMs, the row address only needs to be specified once for accesses within the same page addresses. Successive accesses to the same page of memory only require the selection of a column address, which saves time in accessing the memory. JEDEC, the electronic standards agency, has specified standards for the FPM DRAM.

EDO
Extended Data Output (EDO) was a subsequent DRAM chip technology in a line of innovations which included Nibble Mode, Write Per Bit, and Fast Page Mode. EDO is one step better than Fast Page Mode; for a given speed of chip (i.e. 70ns, 60ns) EDO chips allow the CPU to access memory 10 to 15% faster. A computer system must be designed to utilize the extra efficiency EDO offers. Pentium-class computers using Intel's Triton chip set are designed to use EDO memory. EDO memory will function in a machine that does not recognize EDO, however no performance benefit will be realized.
