Column read enabled three dimensional cross-point memory is optimized to reduce delay time due to partition busy times incurred when reading from a same partition. A column read enabled memory media stores each entry of a logical column of an array of bits in contiguous different physical rows and different physical columns of the cross-point memory array than any other entry of the logical column. Subsets of the contiguous different physical rows are stored in different partitions to reduce the delay time incurred when performing column reads from a same partition to improve media management operation performance.
