Abstract
An apparatus and a system having in-system-programming function are disclosed. The apparatus comprises a non-volatile memory, a controller and a serial interface unit. When the non-volatile memory is to be programmed, the controller will actively catch the program data from an external device via the serial interface unit and save the program data in non-volatile memory. Thus, the programming efficiency is enhanced, an additional programmer is unnecessary, and the production cost can be saved.
Claims20
An apparatus having in-system-programming function comprising:
- a non-volatile memory used for saving program data;
- a serial interface unit used for transmitting the data;
- and
- a controller coupled to said non-volatile memory and said serial interface unit which will actively catch said program data from an external device and save the data in said non-volatile memory when said non-volatile memory is to be programmed.
A system having in-system-programming function including:
- an apparatus having in-system-programming function comprising a non-volatile memory used for saving program data, a serial interface unit used for transmitting the data in serial mode and a controller coupled to said non-volatile memory and said serial interface unit;
- and
- an external device coupled to said apparatus having in-system-programming function to provide said program data;
- wherein, when said non-volatile memory is to be programmed, said controller actively catches said program data from the external device via said serial interface unit and saves the data in said non-volatile memory.
