Abstract

A method for detecting a half-full condition of a first-in, first-out memory array. The method of the invention includes the steps of a) moving a write pointer through the array to write data to alternating rows of the memory array; b) moving a read pointer through the array to read data from the alternating rows of the memory array in first-in, first-out order; and c) providing a half-full indication when the read pointer and the write pointer point to adjacent rows in the memory array. This method eliminates the need to route lines across the array to detect a half-full condition, thereby reducing die and power requirements and offering an increase in speed.
