Abstract
Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a memory device stores data in response to data accesses under the control of a memory control circuit. A solid-state memory circuit and a volatile caching memory circuit provide the memory control circuit with access to a set of common data. A circuit carries primary operating power to the memory device. A backup power circuit has a power module having and securing a power-reservoir circuit. A capacitor holds a charge to provide operating power to the memory circuits to permit transfer of the data from the volatile memory circuit to the solid-state memory circuit. A notification circuit provides an external user indication of the power-reservoir circuit integrity. A circuit-based structure secures the power-reservoir circuit for operation as part of the memory device and facilitates replacement of the power-reservoir circuit.
