Question

Dynamic RAM is more preferable than static RAM, why?

(a) DRAM is of the lowest cost, lowest density

(b) DRAM is of the highest cost, reduced size

(c) DRAM is of the lowest cost, highest density

(d) DRAM is more flexible and lowest storage capacity

I got this question during an interview.

I need to ask this question from Random Access Memory topic in section Memory Devices of Digital Circuits

Answer 1

Correct answer is (c) DRAM is of the lowest cost, highest density

For explanation: The Dynamic Random Access Memory is the lowest cost, highest density random access memory available. Nowadays, computers use DRAM for main memory. However, it’s access time is more compared to SRAM.
