This invention discloses a one-time programmable read-only memory, its control method, and a storage unit, belonging to the field of data storage. When performing a write operation, the invention breaks down the gate oxide layer of the first field-effect transistor specified by the write operation instruction, enabling it to have gate leakage current during operation.
