Question

In which pin does the data appear in the basic DRAM interfacing?

(a) dout pin

(b) din pin

(c) clock

(d) interrupt pin

This question was addressed to me during an internship interview.

I would like to ask this question from DRAM Interfaces in division Memory Systems of Embedded Systems

Answer 1

Right choice is (a) dout pin

Easiest explanation: In the basic DRAM interfacing, the higher order bits asserts the RAS signal and the lower order bits asserts the CAS signal. When the access got expired, the data appears on the dout pin and is latched by the processor.
