Abstract
An embedded memory with system repair data is provided. The embedded memory includes a flash memory unit, a storage unit, and a control unit. The flash memory unit stores an in-system programming (ISP) code. The storage unit stores a system repair code. The system repair code is used for rebuilding the ISP code. The control unit is electrically connected to the flash memory unit and the storage unit. The control unit determines whether the ISP code has been broken and reads the system repair code to rebuild the ISP code when the ISP code has been broken. A system repair method for the embedded memory is also provided, which comprises the steps of determining that the ISP code stored in the flash memory unit has been broken, reading the system repair code stored in the memory unit, and rebuilding the ISP code according to the system repair code.
