Uses several memory units called cells. These cells are packed with very high density. Hence, these chips can hold large amounts of data.
Also known as FPM (fast page mode) DRAM, it comes in 80, 70 or 60 nanosecond (ns) speeds.· Takes two processor wait-states each time a read or write takes place. The advantage is that, it's compatible with just about everything. Disadvantage is that it's the slowest of the memory types currently available and because it isn't in demand, it's now more expensive than faster memory alternatives such as EDO and SDRAM.
Are available on industry standard 30- or 72-pin Single Inline Memory Modules (SIMMs). DRAM is also available in DIMMs.
