Abstract: A dual port random access memory cell is coupled to complementary read/write data bit lines, a read-only data bit line, a read/write address line and a read-only address line. The memory cell includes two two-transistor inverters (36, 38) cross-coupled to form a flip-flop core memory which is coupled to complementary input/output nodes (40, 42). A fifth transistor (44 or 56) has its main electrodes connected between the first input/output node (40) and the first read/write data bit line (BLA) and its gate electrode connected to the read/write address line (ROW SELA or ROW SELA). The sixth transistor (46 or 58) has its main electrodes connected between the second input/output node (42) and the second read/write data bit line (BLA) and its gate electrode connected to the read/write address line (ROW SELA or ROW SELA).

Abstract: A reactive discharge device including an RF cavity with a substantially circular cross-section, with a circular RF field coupled along the longitudinal axis of the cavity. A high volume to surface area ratio volume of reactive gas is created in the cavity. The reactive gas and/or the light created thereby is extracted from the cavity and supplied to a downstream processing area.
