Abstract
An information storage array includes a programmable material at a storage location and a capacitor set. A switching network charges the capacitor set to a first voltage and discharges the capacitor set at a second voltage. The second voltage is greater than the first voltage and it or a waveform derived therefrom is applied to the storage location to thereby change a state of the programmable material.
Claims20
An information storage array comprising:
- a programmable material at a storage location;
- a capacitor set;
- and
- a switching network for charging the capacitor set to a first voltage and discharging the capacitor set at a second voltage, one of the second voltage or a waveform derived therefrom being applied to the storage location to thereby change a state of the programmable material,
- wherein the second voltage is greater than the first voltage.

A method for changing a state of a programmable material at a storage location in an information storage array, the method comprising:
- charging a capacitor set to a first voltage by a switching network;
- generating, by the switching network, a second voltage from the capacitor set, the second voltage being greater than the first voltage;
- and
- applying one of the second voltage or a waveform derived therefrom to the storage location to thereby change a state of the programmable material.
