ABSTRACT:
A storage subsystem, such as a flash memory card, includes a voltage detection circuit that monitors the power signal from a host system to detect anomalies. The voltage detection circuit responds to a power signal anomaly by asserting a signal, such as a busy signal on a standard ready/busy signal line, to block the host system from performing write operations to the storage subsystem during presence of the anomaly. The storage system may also include a backup power source, such as a charge pump circuit, a capacitive array, and/or a rechargeable battery, that provides power to a controller of the storage subsystem during the presence of the anomaly, such that the storage system can complete outstanding operations.
