Bi-directional queue

Some of the embodiments provide a queue comprising a plurality of memory cells arranged in a first column and a second column, the plurality of memory cells also arranged in a plurality of levels, such that ones of the levels include a corresponding memory cell of the first column and a corresponding memory cell of the second column, such that a memory cell of the first column is coupled to at least (i) another memory cell of the first column that is at a different level than a level of the memory cell of the first column and (ii) another memory cell of the second column that is at a same or a different level than the level of the memory cell of the first column; and a control module to selectively add data, selectively remove data, and selectively transfer data between the memory cells of the queue.
