Tracking dynamic memory de-allocation using a single configuration table having a first register and a second register includes setting the first register as an active register, initiating a de-allocation of desired storage increments from a memory partition, setting the storage increments in the second register as invalid, purging all caches associated with the single configuration table, setting the second register as the active register and the first register as an inactive register, setting the desired storage increments in the first register as invalid, switching the active register from the second register to the first register to complete memory de-allocation using the single configuration table.
