The 1990s were a weird time. They were filled with both the best and worst of technology. Well, where are the bad ones we all have forgotten about. We had more than one president, the internet was beginning to take off, and we all had to watch the world's first-ever live webcast on TV (that was a thing). We also had plenty of other technological marvels: like EDO memory! EDO memory is a modified form of Fast Page Mode (FPM) memory that allows timing overlap between each new data access cycle. In EDO, a new data cycle is started while the data output of the previous cycle is still active. This process of cycle overlapping, called pipelining, increases processing speed by about ten nanoseconds per cycle, increasing computer performance by about 5 percent compared to the version using FMP. One of the things that make Extended Data Out (EDO) RAM so special is not just that it's fast but also that it can be used in a variety of different ways. It can be used as standard DRAM, which means it can't be accessed as fast as EDO RAM. It can also be used to create a hybrid memory system that combines the speed and power of EDO RAM with synchronous DRAM (SDRAM) reliability. This approach is known as Hyper Page Mode enabled DRAM or HP-EDO for short. HP-EDO uses SDRAM to store data, while EDO RAM is used to access it quickly. This works well because SDRAM has high capacity but relatively low access speeds, so you don't want it to handle your most frequently accessed data. If you use HP-EDO, you can store your least frequently accessed data in SDRAM and give your EDO memory more room to do what it does best: move around data at lightning speed.
