Abstract
A microwave oven including a keyboard, a microwave generating circuit, and a microprocessor for controlling the same. The keyboard has function keys for setting cooking conditions, numeral keys, and a memory key for commanding storage and retrieval of cooking information from a random access memory. The microprocessor is responsive to an operation of the memory key to transfer cooking information set by the function keys and numeral keys, from a buffer memory to a particular storing stage of the random access memory, according to the setting of a number of flag bits in the buffer memory. New cooking information is then transferred to the buffer memory from the next storing stage of the random access memory, and the flag bits are reset to indicate which storing stage corresponds to this information. The cooking and stage identifying information in buffer memory is read out by a display, and the displayed cooking information may be changed without affecting the content of the other storing stages in the random access memory.
