Techniques for reducing impact of array disturbs in a semiconductor memory device |
摘要 |
Techniques for reducing impact of array disturbs in a semiconductor memory device are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for reducing impact of array disturbs in a semiconductor memory device by increasing the refresh rate to the semiconductor memory device based at least in part on a frequency of active operations. The method may comprise receiving a first refresh command including a first subarray address to perform a first refresh operation to a first logical subarray of memory cells associated with the first subarray address. The method may also comprise receiving a second refresh command including a second subarray address to perform a second refresh operation to a second logical subarray of memory cells associated with the second subarray address, wherein the second refresh command is received after a time period from the reception of the first refresh command. The method may further comprise performing a number of concurrent refresh operations during the time period. |
