A battery management system having configurable batteries is disclosed. The battery management system generally includes (a) one or more cell control units, each cell control unit configured to control and/or balance a charge in a plurality of battery cells, and (b) a master controller in electrical communication with cell control unit(s). The cell control unit(s) as a whole include one or more switches, configured to be electrically connected to a first battery cell of a plurality of battery cells, and a resistor, a capacitor or an inductor electrically (i) connected to one switch and (ii) connected or connectable to a second battery cell. The master controller is configured to open or close each switch. The configurable battery generally includes a plurality of battery cells and switches configured to connect or disconnect the plurality of battery cells in a configurable or predetermined manner.

In a non-volatile electric memory system a card-like memory unit () and a read/write unit () are provided as physically separate units. The memory unit () is based on a memory material () that can be set to at least two distinct physical states by applying an electric field across the memory material. The read/write unit () comprises contact means () provided in a determined geometrical pattern enabling a definition of memory cells in memory unit () in an initial write operation, the memory cells being located in a geometrical pattern corresponding to that of the contact means (). Establishing a physical contact between the memory unit () and the read/write unit () closes an electrical circuit over an addressed memory cell such that read, write or erase operations can be effected. The memory material () of the memory unit () can be a ferroelectric or electret material that can be polarized into two discernible polarization states, or it can be a material with a resistive impedance characteristic such that a memory cell of the material can be set to a specific stable resistance value by the application of an electric field.
