    摘要: A semiconductor device structure is embedded within a semiconductor chip that calibrates a photon-emission luminosity scale by running multiple known currents through the device. The method comprises embedding at least one photon emission device in an integrated circuit having at least one functional device. A control current is applied to the at least one photon emission device. The photon emission intensity produced by the at least one photon emission device is captured. The current density of the at least one photon emission device is calculated. A test current is applied to the at least one functional device. The photon emission intensity produced by the at least one functional device is captured. The current density of the at least one functional device is estimated based on a comparison with the calculated current density of the at least one photon emission device.

    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.
