Latest Patents

One of Reidar Stief's latest patents is a circuit configuration for receiving a data signal. In this invention, a clock-synchronously operated semiconductor memory, particularly a DDR SDRAM, reads data in sync with a data strobe signal during normal operation. During test mode, a DQ receiver is supplied with the operating clock signal instead of the DQS signal, allowing for a direct signal path to bridge a downstream memory element. This innovation ensures that the data signal supplied to the memory cell array is available immediately after a write command is applied.

Another significant patent involves a circuit for synchronizing signals during the exchange of information between circuits, especially between computer chips. This configuration includes a delay locked loop (DLL) circuit that synchronizes an internal clock with an external clock based on the phase difference between the two. The response sensitivity of the DLL circuit is defined by a filter, which allows for renewed synchronization only after multiple phase change events occur. The filter is designed to be of a variable configuration, enhancing its adaptability.
