Arrays, Memory and Strings in Verilog?

Arrays: Collection of objects of the same data type.

e.g.:

reg [7:0] arr; ==> 8-bit vector (or) bus of reg data type 

reg arr [7:0]; ==> array of 8 one-bit element

Memory: A memory structure can be created using arrays.

-> Memory structure using a 2-dimensional array: reg [0:7] memo [0:3];

-> Memory structure using a multi-dimensional array: reg [0:7] memo [0:3] [0:3] [0:3];

Strings: Group of characters enclosed in double quotation.

myString = "Welcome to VLSI Digest";
