An associative array of memory cells is arranged with its read cells interleaved with its storage cells to reduce the physical space required by the array. Two rows of read cells have four rows of storage cells on each side thereof except that the uppermost row of the read cells in the array has only two rows of the storage cells thereabove and the lowermost row of the read cells in the array has only two rows of the storage cells therebelow. One half of the read cells in each row of the read cells provides an output for one of the two adjacent rows of the storage cells.
