摘要： Disclosed are embodiments of memory circuit having two discrete memory devices with two discrete memory arrays that store essentially identical data banks. The first device is a conventional memory adapted to perform all maintenance operations that require read functions (i.e., all update and refresh operations). The second device is a DRAM-based CAM device adapted to perform parallel search and overwrite operations only. Performance of overwrite operations by the second device occurs in conjunction with performance of maintenance operations by the first device so that corresponding memory cells in the two devices store essentially identical data values. Since the data banks in the memory devices are essentially identical and since maintenance and parallel search operations are not performed by the same device, the parallel search operations can be performed without interruption. Also disclosed are embodiments of an associated design structure and method.

摘要： A circuit containing a parallel connection of a first sub-circuit and a second sub-circuit is provided. The first sub-circuit comprises a serial connection of a first field effect transistor having a first threshold voltage and a first voltage dividing device. The second sub-circuit comprises a serial connection of a second field effect transistor having a second threshold voltage, which is different from the first threshold voltage, and a second voltage dividing device. The voltage between the first field effect transistor and the first voltage dividing device is compared with the voltage between the second field effect transistor and the second voltage dividing device so that a signal may be generated at a temperature at which the ratio of a performance parameter such as on-current between the first and second field effect transistors crosses over a predefined value. The signal may be advantageously employed to actively control circuit characteristics.
