Fast Page Memory

Fast Page Memory (FPM) DRAM is slightly faster than conventional asynchronous DRAM. The way that the memory controller accesses the RAM is slightly different. Instead of sending a row and a column address for each access, FPM works by sending a row address only once, which allows for many accesses to the system memory in locations near each other, significantly improving access time delay.

However, of all of the new DRAM technologies in use in modern PC's, FPM DRAM is the slowest. It should not be used in any computer that has a higher bus speed than 66MHz. It is the easiest to configure however, in that it does not take any special BIOS settings to use FPM DRAM.
