What Does Dynamic Random Access Memory (DRAM) Mean?
Dynamic random access memory (DRAM) is a type of random-access memory used in computing devices (primarily PCs). DRAM stores each bit of data in a separate passive electronic component that is inside an integrated circuit board. Each electrical component has two states of value in one bit called 0 and 1. This captivator needs to be refreshed often otherwise information fades. DRAM has one capacitor and one transistor per bit as opposed to static random access memory (SRAM) that requires 6 transistors. The capacitors and transistors that are used are exceptionally small. There are millions of capacitors and transistors that fit on one single memory chip.
Techopedia Explains Dynamic Random Access Memory (DRAM)
DRAM is dynamic memory and SRAM is static memory. The DRAM chips on a circuit board need to refresh every few milliseconds. This is done by rewriting the data to the module. Chips that need refreshing are volatile memory. DRAM accesses the memory directly, holds memory for a short period and loses its data when the power is shut off. SRAM is volatile memory that is static and does not need refreshing. Because SRAM is a lot faster, it is used in registers and cache memory. SRAM keeps data and performs at higher speeds than DRAM. Although SRAM is faster, DRAM is used more often on the motherboard because it is a lot cheaper to manufacture.
