Question

The magnetic core memories have been replaced by semiconductor RAMs, why?

(a) Semiconductor RAMs are highly flexible

(b) Semiconductor RAMs have highest storing capacity

(c) Semiconductor RAMs are smaller in size

(d) All of the Mentioned

The question was posed to me during a job interview.

Question is taken from Random Access Memory in section Memory Devices of Digital Circuits

Answer 1

The correct option is (d) All of the Mentioned

Explanation: RAM is a volatile memory, therefore it stores data as long as power is on. RAM is also known as RWM (i.e. Read Write Memory). The magnetic core memories have been replaced by semiconductor RAMs because of smaller in size, high storing capacity as well as flexibility.
