Definition of "DRAM" |
Dynamic RAM: Random-Access Memory that uses a continuous clock. Unlike SRAM, when DRAM is no longer clocked, its data is lost. / A type of RAM that maintains its content 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 and slower than SRAM because of the longer access times. [DRAM Manufacturers] / Dynamic Random Access Memory, Dynamic RAM, Database of Recorded American Music, / Dynamic random-access memory is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. Since even "nonconducting" transistors always leak a small amount, the capacitors will slowly discharge, and the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to static random access memory (SRAM) and other static types of memory. / DRAM is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit.
