In one embodiment, a memory controller may be configured to perform a logic operation, such as a hash function, on selected address bits to produce a bit of channel or bank select. The selected address bits for each select bit may differ, and may be programmable in some embodiments. By combining selected address bits to produce the select bits, the distribution of addresses in a set of regular access patterns may be somewhat randomized to the channels/banks. In one implementation, each select bit may have a corresponding programmable bit vector that specifies the address bits to be included for that select bit. Accordingly, any subset of the address bits may be included in any select bit generation.
