Abstract
A random number generator selects addresses while a ‘scoreboard’ bank of registers (or bits) tracks which addresses have already been output (e.g., for storing or retrieval of a portion of the data.) When the scoreboard detects an address has already been output, a second address which has not been used yet is output rather than the randomly selected one. The second address may be selected from nearby addresses that have not already been output.
