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.

A memory apparatus embedded with a computing function and an operation method thereof are provided. The memory apparatus includes a memory array, a plurality of data flow controllers, a plurality of computation circuits, a data bus, and a control logic circuit. The memory array includes a plurality of block groups having a plurality of memory blocks. Each of the data flow controllers selects a transmission path of data of each memory block according to a corresponding one of the data flow control signals. In a computation mode, the computation circuit computes first data from the corresponding memory block. In a normal mode, second data is transmitted between the data bus and the corresponding memory block. The data flow controller transmits the first data from the corresponding memory block to the computation circuit according to the data flow control signal provided by the control logic circuit to compute the first data.
