Method and device for updating firmware resident in electrically erasable programmable read only memory
专利汇可以提供Method and device for updating firmware resident in electrically erasable programmable read only memory专利检索，专利查询，专利分析的服务。并且PURPOSE: To update a firmware without altering the firmware by providing a control logic device for maintaining the firmware of an amount selected beforehand in a protective area. CONSTITUTION: This device is constituted of a memory device 16, the control logic device 15 provided with inputs 13 and 11A and an output 14 connected to the memory device 16 and an input device 10 connected to the inputs 11A and 13 of the control logic device 15 for generating addresses. Then, the control logic device 15 enables access to the non-protective area 36 selected beforehand of the memory device 16 when the input device 10 generates the address of the non-protective area 36 selected beforehand of the memory device 16. However, when the input device 10 generates the address inside the protective area 37 selected beforehand of the memory device 16, the access to the protective area 37 selected beforehand of the memory device 16 is denied. Thus, the alteration of the firmware 15 prevented and the firmware is updated.，下面是Method and device for updating firmware resident in electrically erasable programmable read only memory专利的具体信息内容。
