Download Solution PDFThe correct answer is DRAM.
Key Points
- Dynamic Random-Access Memory (DRAM) is a type of random access memory used in most modern computer systems.
- DRAM stores each bit of data in a separate capacitor within an integrated circuit.
- Because capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. This is why DRAM is called "dynamic".
- DRAM is used in main memory because it is relatively inexpensive and can store large amounts of data.
- It is slower than Static RAM (SRAM), but its cost-effectiveness and density make it suitable for main memory applications.
Additional Information
- DRAM technology has evolved over the years, with various generations such as DDR (Double Data Rate), DDR2, DDR3, DDR4, and the latest DDR5.
- Each new generation of DRAM provides improvements in speed, power consumption, and data transfer rates.
- DRAM is volatile memory, meaning it loses its data when the power is turned off.
- In contrast, SRAM is faster but more expensive and is typically used for cache memory.
