Abstract
A request to perform a memory operation addressed to a first address corresponding to a first logical unit of logical units of a memory is received. Address mask data that corresponds to the logical units is identified. Multiple transformed addresses are determined using the first address and the address mask data. The transformed addresses can include a target address corresponding to the first logical unit and additional addresses corresponding to other logical units. The memory operation is performed at the target address corresponding to the first logical unit and dummy memory operations are performed at the additional addresses corresponding to the additional logical units.
