INSERTION-OVERRIDE COUNTER TO SUPPORT MULTIPLE MEMORY REFRESH RATES |
| 摘要 |
A memory refresh method includes determining positions at which to insert refresh operations of weak rows of a memory block among regularly scheduled refresh operations of normal rows of the memory block. The refresh operations occur at a substantially constant refresh rate. The positions at which to insert are based on an actual weak page address. The method also includes performing inserted refresh operations at the determined positions to coordinate distribution of the inserted refresh operations among the regularly scheduled refresh operations. |
