Which of the following is one of the basic characteristics of DRAMs?
A) DRAMs are simpler devices than other type memories.
B) DRAMs have a broader dynamic storage range than other types of memories.
C) DRAMs must have a constantly changing input.
D) DRAMs must be periodically refreshed in order to retain data.
Question 2
What is the major difference between SRAM and DRAM?
A) Dynamic RAMs are always active; Static RAMs must rest between data read/write cycles.
B) The only difference is the terminal from which the data is removed: from the FET Drain or Source.
C) DRAMs must be periodically refreshed.
D) SRAMs can hold data via a static charge, even with power off.
