Abstract
A method for operating a dynamic memory is provided, and the method includes the following steps. A refresh operation is performed on the dynamic memory according to predetermined interval time T, an operation command is received in real time at the same time, a read operation is performed on a selected memory cell according to position information of the selected memory cell in the operation command when the operation command is received, and state data read in the read operation is temporarily stored in a read buffer. The interval time T is less than time t required for a voltage value of a capacitor in the memory cell to drop to a critical capacitor voltage value for the read operation to correctly read the state data of the memory cell during a write operation. According to operation command type information in the operation command, corresponding operations are performed on the selected memory cell.
