Dynamic RAM (DRAM)

DRAM (pronounced 'dee-ram') has, until recently, been the most common type of memory in PCs. Compared to other forms of integrated circuits, DRAM isn't complex and, as a result, is not expensive. However, its design also requires that it be refreshed regularly or it loses its contents. DRAM is also the slowest of the memories, clocking with access speeds around 50 nanoseconds (ns) or higher (higher, in this case, means slower). Older DRAM had an access speed of about 120 ns.

DRAM memory comes in the following package forms:
