Abstract
A flash controller and a control method for the flash controller. The flash controller comprises an instruction bus interface, a data bus interface, a configuration register, an erase access filter module, a read/write access filter module and a flash control module. The read/write access filter module is configured to receive control information and determine whether the read/write access is sent to the flash control module or not. The erase access filter module is configured to receive control information and determine whether the erase access is sent to the flash control module or not. The flash control module is configured to complete an access to a flash memory. The present disclosure is used to protect programs from being stolen by a client, and also protect against a situation where companies collaboratively developing a program are able to steal programs from one another.
