Question

If a RAM chip has n address input lines then it can access memory locations upto __________

(a) 2^(n-1)

(b) 2^(n+1)

(c) 2^n

(d) 2^2n

The question was asked in a national level competition.

I would like to ask this question from Random Access Memory topic in division Memory Devices of Digital Circuits

Answer 1

The correct option is (c) 2^n

Easiest 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). If a RAM chip has n address input lines then it can access memory locations upto 2^n.
