DRAM Circuit Design. Fundamental and High-Speed Topics
Dynamic random-access memory DRAM is a type of random access semiconductor memory that stores each bit of data in a memory cell consisting of a tiny capacitor and a transistor , both typically based on metal-oxide-semiconductor MOS technology. The capacitor can either be charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1. The electric charge on the capacitors slowly leaks off, so without intervention the data on the chip would soon be lost. To prevent this, DRAM requires an external memory refresh circuit which periodically rewrites the data in the capacitors, restoring them to their original charge. This refresh process is the defining characteristic of dynamic random-access memory, in contrast to static random-access memory SRAM which does not require data to be refreshed. Unlike flash memory , DRAM is volatile memory vs. However, DRAM does exhibit limited data remanence.
Powered by Discuz! With its ability to produce high product volumes and low pricing, it forces solid-state memory manufacturers to work aggressively to cut costs while maintaining, if not increasing, their market share. As a result, the state of the art continues to advance owing to the tremendous pressure to get more memory chips from each silicon wafer, primarily through process scaling and clever design.
