Abstract
An erase-on-demand memory cell() includes a memory layerand a heating layerthat can heat memory layerto at least an erase-effective temperature, to erase its data contents. Memory chips() and electronic systemsinclude cells(). Electronic systems() include logic circuitryto issue a signal to initiate heating. Electronic systems() include memory chips() with one or more erase-on-demand memory cells() that include a memory layer. One or more reservoirsstore chemicals. One or more valvesretain the chemicals, and respond to a signal to open, reacting the chemicals and/or exposing memory layersto the chemicals. A method of erasing data contents of memory cells includes determining existence of an erase demand scenario, generating a signal in response to the erase demand scenario, and actuating erasure of the memory cells upon issue of the signal.
