Abstract
An electronic device and a control method for memory refresh operation thereof are provided. The electronic device includes a memory and a controller. The memory includes a plurality of timers, a plurality of buffers and an interrupt signal generator. Each of the buffers is 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 corresponding timer. The interrupt signal generator generates an interrupt signal corresponding to an auto refresh operation according to the timing result trigger signal, a non-internal self-refresh mode signal and a non-accessing status. The controller receives the interrupt signal and transmits an auto refresh command to the memory according to the interrupt signal to enable the memory to perform the auto refresh operation.
