Abstract: A method for estimating degradation of a rechargeable battery, includes determining a coulomb count value by integrating a charging/discharging current of the battery, monitoring a state of the battery, detecting that the battery is charged/discharged with a predetermined amount of charges, based on the coulomb count value, and changing an index X indicating degradation of the battery by a variation ?X in accordance with the state of the battery, which is measured in a period during which the battery is charged/discharged with the predetermined amount of charges, if the charging/discharging of the battery with the predetermined amount of charges is detected.

Abstract: The present invention improves the detection accuracy of the state of charge of a battery. A coulomb count value CC is generated by integrating a charge/discharge current IBAT of a battery (S100). An SOC value SOC1 is calculated (S102). Based on an SOC-OCV characteristic predetermined for the battery, an OCV value OCV1 corresponding to the value SOC1 is generated (S112). A voltage VBAT of the battery is detected (S104). A voltage drop VDROP1 between OCV1 and a detected value VBAT1 of the voltage VBAT is generated (S114). A value OCV2 greater than the minimum operating voltage of the system by ?V, which corresponds to the voltage drop VDROP1, is generated (S116). Based on the SOC-OCV characteristic, an SOC value SOC2 corresponding to OCV2 is generated (S118). Based on the value SOC2, at least one of the values SOC1, CC, CCFULL, and SOC-OCV characteristics is corrected.

Abstract: A semiconductor memory device includes a memory which comprises a confidential information area storing confidential information and a flag. A controller reads the flag from the memory when instructed to erase or write data in the confidential information area, determines whether the flag is set, erases or writes data in the confidential information area when the flag is clear, and abandons a process requested by an erase or write instruction when the flag is set. An authenticator uses data in the confidential information area to execute an operation for authentication. A management information area may store management information for associated pages. The flag may include a bit string and a complementary bit string to improve reliability of the flag. The confidential information area may store dummy data when the memory is used for uses other than an application with an authentication function, so no problem arises using a normal controller.
