1. An electronic device, comprising:
a memory, comprising:
a plurality of timers;
a plurality of buffers, respectively coupled to the timers, and each of the buffers being configured to store at least one word line information and generate a refresh word line information according to a timing result trigger signal of each of the corresponding timers; and
an interrupt signal generator, generating an interrupt signal corresponding to an auto-refresh operation according to a plurality of the timing result trigger signals of the timers, a non-internal self-refresh mode signal, and a non-access state; and
a controller, coupled to the memory, receiving the interrupt signal and transmitting an auto-refresh command to the memory according to the interrupt signal to enable the memory to perform the auto-refresh operation.
