Abstract: A programmable, sequential logic array for performing logical operations within a memory array, including an input storage array having addressable locations for storing input control words, input means for receiving a plurality of input signals and control words from the input storage array and producing signals indicating the relationship between conditions of the input signals and conditions represented by the control words, output means for providing binary output signals, an output storage array having addressable locations for storing output control words for controlling a state of the output means, a next address storage array for identifying a next address from one of a plurality of fields within the next address array, address generation means for receiving address signals from the next address storage array and for applying the address signals to address circuits of the input storage array, the output storage array, and the next address storage array, coding means for coding status of lines comprisi

Abstract: Operation of an AC plasma display panel requires the three control operations of write, erase, and sustain. Sustain, write and erase signals are stored in a plurality of sections in a storage device and the sections are selectively accessed according to the specific operation to be provided to the plasma panel display. Switching between the sections in the storage device is accomplished without signal discontinuity in the sustain, write, and erase signals used to drive the illuminable cells. The sustain operation is recycled during those periods when no write or erase operation is being done.
