how to construct 4x2 matrix taking value 0 and 1 randomly? No rows should be repeated.

for example 4x2 matrix, the output should be [1 0;1 1;0 1; 0 0]. In this matrix no rows are repeated. I uses the code randi([0,1],4,2). I got 4x2 matrix but getting repeated row like [1 0;1 1;1 0; 0 0].Here, row1 and row3 are same, which is not acceptable.

please help to construct the matrix without any repeation of rows.
