A battery grid includes a frame that includes a top element, a bottom element, a first side element, and a second side element. A refresh transistor has a source coupled to one of the plurality of bitlines, a control gate coupled to a dynamic random access memory wordline and a drain. The compositions include a water control additive that is prepared by reacting a soluble sodium silicate and a hydrolysable organosilane compound to produce silanol that reacts and forms a bond with the formation thereby producing a binding polysiloxane. Also, when the row addresses of the memory writing and the display reading are different from each other, the write address and data are stored in the reservation buffer and also the display reading is executed.
