Abstract
Disclosed are a method for writing data into a first storage on a chip and a system thereof. The method includes storing an initial firmware into a second storage on the chip, programming the first storage according to a specific data by utilizing the initial firmware, and blocking further programming operations applied to at least part of the specific data after the specific data is successfully stored in the first storage. Therefore the invention can save the external pin connections of the chip to prevent computer hackers from accessing or changing the content of the storage.
Claims28
A method for writing data into a first storage on a chip, comprising:
- storing an initial firmware into a second storage on the chip;
- programming the first storage according to a specific data by utilizing the initial firmware;
- and
- after the specific data is successfully stored in the first storage, blocking further programming operations applied to at least part of the specific data.
A method for writing data into a first storage on a chip, comprising:
- storing an initial firmware into a second storage on the chip;
- and
- programming the first storage according to an eFuse data by utilizing the initial firmware.
A system for data programming, comprising:
- a first storage, formed on a chip;
- a second storage, formed on the chip, for storing an initial firmware;
- and
- a control module, formed on the chip and coupled to the first storage and the second storage, for programming the first storage according to a specific data by utilizing the initial firmware, and after the specific data is successfully stored in the first storage, blocking further programming operations applied to at least part of the specific data.
