Method of controlling a refresh operation of PSRAM and related device |
摘要 |
A plurality of refresh requests are generated at a predetermined period shorter than the longest time during which a PSRAM is able to retain a data without being refreshed. For two consecutive first and second refresh requests, the second refresh request is ignored if the interval between the first and the second refresh requests is not larger than a predetermined duration. The first refresh request is delayed if the first refresh request conflicts with an external command of the PSRAM. |
