Abstract
A controller and a method of updating parameters on the same. The controller includes an embedded non-volatile memory, a programming circuit, an embedded SRAM, a MCU (Micro Computer Unit), and a memory controller. The embedded non-volatile memory has a program code block for storing program codes to be executed by the MCU, and a data block for storing the parameters. The MCU writes the parameters into the data block of the flash memory through the memory controller, or reads data in the data block of the non-volatile memory through the memory controller. Because the controller does not need to employ an external EEPROM, the cost can be reduced and the speed for accessing the parameters can be increased.
