PL/SQL allocates memory for the variable's at runtime or at compile time..

Answer / gaurav

For a CHAR variable, PL/SQL allocates at compile time enough memory for the maximum size.
For a VARCHAR2 variable, memory allocation depends on maximum size:
If the maximum size is less than 4,000 bytes, PL/SQL allocates at compile time enough memory for the maximum size.
If the maximum size is 4,000 bytes or more, PL/SQL allocates at run time enough memory for the actual value.

Thus, PL/SQL optimizes smaller VARCHAR2 variables for performance and larger ones for efficient memory use. ( from oracle doc)
