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 m… WebReading from DRAM. When the CPU wants to access a row in memory (e.g., row 1), we have to activate the row and the activated row is copied to the row buffer, then the value from the row buffer is returned to the CPU. If the CPU wants to access a different row, the process starts again, evicting the previous row from the row buffer.
