Memoryless System
Definition: A system is said to be memoryless if its output at a particular point in time depends only on the input at that same time.
Example: $ y[n]=x^2[n]+17n-3 $
System With Memory
Definition: A system is with memory if its output at a particular point in time depends on inputs at more than just this time.
Example: $ y[n]=x^2[n+2]+17n-3 $
Jayanth's Comments: The example given for the system with memory is wrong. Because (17n-3) is a scalar and hence it is a memory-less system.
