In an embodiment, a data scramble/descramble circuit for a memory may employ multiple scramble circuits that may provide randomization of data across both rows and columns of a memory array. The first circuit may receive at least a portion of the address of the row, and may produce an output value by logically operating on the portion of the address. The second circuit may receive the output of the first circuit (or a portion thereof) as a seed, and may scramble the data to be written to memory. In one embodiment, a least significant portion of the address may be operated upon by the first circuit (e.g. the least significant byte), which may be most likely to change from row to row as compared to other portions of the address.
