Maybe he is asking HOW memcached allocates memory? I'm no expert but from what I understand memcached will allocate memory in "slabs" of a fixed length. If the data to be saved is smaller then the slab, the entire slab will be used. Once a slab is no longer used, memcached will still hold on to this allocation in order to re-use it at a later point in time.
With the slab allocation you also prevent fragmentation of your memory, increasing read/write times.
