| Refresh Rate |
| A memory module is made up of electrical cells. The refresh process recharges these cells, which are arranged on the chips in rows. The refresh rate refers to the number of rows that must be refreshed. The common refresh rates are 1K, 2K, 4K and 8K. Some specialty designed DRAMs feature self refresh technology, which enables the components to refresh on their own - independent from the CPU or external consumption, and it is commonly used in notebook computers and laptop computer. |
