A lawn mower, wherein the cutter system of the lawn mower needs to judge whether the start pulse and the start signal of the cutter switch are valid at the same time under the condition that the seat switch is closed, and the cutter system will be started, only the two conditions are met at the same time, thus not only improving the safety when the cutter system is started, but also the startup of the cutter system can be completed automatically, saving time and labor, and reducing the operator's operation difficulty.

A read-only memory includes a plurality of storage units arranged in an array. The read-only memory includes two kinds of storage units with different structures, the two kinds of storage units with different structures are a first MOS transistor and a second MOS transistor. A source and a drain of the first MOS transistor have the same type, a source and a drain of the second MOS transistor have inverse type. These two kinds of MOS transistors can be used to store binary 0 and 1 respectively. In the manufacturing method of the read-only memory, the same type of drain and source can be manufactured simultaneously, no extra mask plate is needed, so the extra mask plate of a conventional read-only memory can be saved.
