Increased densities of DRAM integrated circuits have led to physically smaller memory cells containing less charge, resulting in lower operational noise margins, increased rates of electromagnetic interactions between memory cells, and greater possibility of data loss. As a result, disturbance errors have been observed, being caused by cells interfering with each other's operation and ma…
