  • Integrated circuit using a back gate voltage for burn-in operations
    Patent number: 5963779
    Abstract: Integrated circuit architectures and methods of operation are provided that allow for the connection of a negative back-gate bias voltage to substrate contacts 24, 90, and 56 during burn-in operations. Accordingly, latch up conditions are prevented during burn-in operations when a circuit is especially vulnerable to such conditions and a grounded substrate is provided to allow for the most efficient operation of the circuit during normal conditions.

  • Two-port two-transistor DRAM
    Patent number: 5007022
    Abstract: A DRAM array having a number of two-port cells (10) arranged to permit the simultaneous read and write operations of different cells within the array. Each column of the array includes a refresh circuit (40) which is responsive to a four-phase clock for carrying out refresh operations which are transparent to the programmer. When used in microcomputer applications having four-phase clocks, the DRAM array of the invention functions similar to a static RAM, in that refresh is automatically undertaken.
