Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

Our Problem bībo be two-bit binary Let A = a1 ao and B = numbers. A and B can take on values from 0 to 3 (for example, A = 2 when aj ao = 10. Let C be a two bit binary number whose value equals the magnitude of the difference A – B. We have C = c¡c0 = |A – B|. (This means that if B is larger than A then you consider B-A.) You are to design a circuit which accepts A and B (i.e., aj aob¡bo) as inputs and outputs the result C = c¡c0. The circuit thus has four inputs and two outputs. For example, the circuit should output cjco = 10 when ajao = 01 and bibo = 11 (C = 2 when A = 1 and B = 3). -
