Abstract

A method and apparatus for greatly simplifying the circuitry needed to handle the bubbleback situations in FIFO memories includes an additional row of cells added to the memory array. By adding an extra row of memory cells, the read and write pointer are only on the same row when the FIFO is operating near the empty boundary or in fallthrough mode.
