  • Patent number: 10387597
    Abstract: A first and second set of simulation information of a circuit design may be received. Energy consumption values associated with signals may be calculated for each of the first and second sets of simulation information of the circuit design. The energy consumption values associated with the transitions of the plurality of signals for each time point of a plurality of time points may be aggregated based on when each of the transitions of the signals occurs for each of the first and second sets of simulation information. Furthermore, a possible Differential Power Analysis (DPA) leak may be identified at one of the time points based on a difference in aggregated energy consumption values between the first and second sets of simulation information.
    Type: Grant

  • Patent number: 9747230
    Abstract: A memory system includes a two memory modules and a memory controller. The memory modules each include at least a first memory package corresponding to a first number of memory ranks (e.g. one memory rank) and a second memory package corresponding to a second number of memory ranks (e.g. two memory ranks) that is greater than the first number of memory ranks. For each module, the memory packages may be asymmetrically staggered such that one memory package is further from the memory controller than the other memory package. The memory controller is coupled to the memory packages of both modules via a common data line and generates control information for controlling the on-die termination (ODT) of the memory packages.
