destructive readout (DRO)

Destructive Readout (DRO) means destructive reading.

This refers to memory technologies in which the memory cell loses its information when it is read out. The historical core memories are an example of this. As soon as a core memory cell was read out, the remanence could drop sharply and the stored bit

was lost. This was referredto as Destructive Readout (DRO), and in

order to preserve the destroyed information, the data bits were re-read into the memory cell after the destructive readout.
