A method to refresh copies of firmware based on ages of those copies of the firmware is described. The method includes determining, by a memory subsystem, an age of a first copy of firmware, which is stored in the memory components of the memory subsystem, is greater than a refresh interval, wherein the age of the copy of firmware is tracked in a firmware age table. In response to determining that the age of the first copy of the firmware is greater than the refresh interval, the memory subsystem refreshes the first copy of the firmware in the memory components. Further, the memory subsystem updates the age of the first copy of the firmware in the firmware age table in response to refreshing the first copy of the firmware.
