DRAM is a type of RAM that maintains its content only as long as the data
stored in the device is refreshed at regular intervals.
DRAM requires a refresh cycle every few milliseconds in order to retain its data. The
data is stored in a capacitor which slowly leaks, the refresh cycle
re-charges the capacitor.
DRAM is cheaper than SRAM but DRAM is slower because
of the longer access times.
Many of the different types of DRAM are
listed below, followed by a list of manufacturers.
