Which of the following memories must be refreshed many times per second?
Question
Which of the following memories must be refreshed many times per second?
Solution
The type of memory that must be refreshed many times per second is Dynamic Random Access Memory (DRAM). DRAM stores each bit of data in a separate capacitor within an integrated circuit. Because these capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Therefore, DRAM needs to be refreshed many times per second to retain the data.
