The invention discloses a PSRAM time sequence calibration system and method, electronic equipment and a storage medium. The PSRAM time sequence calibration system comprises a PSRAM time sequence calibration operation module, a PSRAM control module, a PSRAM storage entity, a PSRAM time sequence calibration module and an EFUSE storage control entity. The PSRAM time sequence calibration operation module is used for carrying out PSRAM time sequence calibration operation; the PSRAM control module is used for completing memory access of application programs or various data in the PSRAM storage entity; the PSRAM storage entity is used for storing various application programs or data; the PSRAM time sequence calibration module is used for writing a specific test data set into a PSRAM storage entity, reading the specific test data set and verifying the specific test data set so as to detect the eye width of the current PSRAM communication time sequence, and judging whether the current eye width ...
