1.	What is the major difference between DRAM and SRAM?(a) Dynamic RAMs are always active; static RAMs must reset between data read/write cycles(b) SRAMs can hold data via a static charge, even with power off(c) The only difference is the terminal from which the data is removed—from the FET Drain or Source(d) DRAMs must be periodically refreshedThe question was posed to me during an interview.My enquiry is from Read Only Memory (ROM) in chapter Memory Devices of Digital Circuits
Answer» Right option is (d) DRAMs MUST be PERIODICALLY refreshed The explanation is: DRAMs must be periodically refreshed so that it can store the new information. DRAMs are SLOWER compared to SRAMs as the access time for SRAM is less than that of DRAM.
