Abstract

The invention relates to a data writing method and writing device of an electrically erasable programmable read-only memory. The method is implemented in coordination with an operating device. The operating device comprises the electrically erasable programmable read-only memory with a writing prevention pin, wherein the writing prevention pin is loaded with a writing prevention voltage; when the writing prevention voltage is higher than the system voltage, the operating device is in a writing prevention mode; and when the writing prevention voltage is lower than the system voltage, the operating device is in a writing mode. The method comprises the following steps: (a) electrically connecting the writing device with the operating device; (b) boosting the system voltage to be a new system voltage so that the writing prevention voltage of the operating device is lower than the boosted system voltage and the operating device is in the writing mode; and (c) writing updating data to the operating device. The data writing method and writing device provided by the invention have the advantages that: updating data can be automatically written by a simple operation of connecting the writing device with the operating device, thus the current complicated program data updating flow is simplified.

Description

technical field [0001] The invention relates to an update data writing method and a writing device, in particular to a data writing method and a writing device of an electrically erasable programmable read-only memory which simplifies the updating process. Background technique [0002] refer to figure 1 , an operating device 9 for games (such as a Wii remote controller) can be electrically connected to an expansion device 7, and its related application can refer to the description of US Patent Publication No. 20070072680. [0003] The operating device 9 has a core circuit 90, an EEPROM 91 carrying a program data 911 required by the operating device 9, and an expansion interface 921; correspondingly, the expansion device 7 is also equipped with an electrical connection The connection interface 711 of the expansion interface 921 . [0004] In terms of actual circuit connection, the pins of the core circuit 90 electrically connected to the EEPROM 91 include WP (write-proof) p...
