  • Publication number: 20150170729
    Abstract: Examples are disclosed for accessing a dynamic random access memory (DRAM) array. In some examples, sub-arrays of a DRAM bank may be capable of opening multiple pages responsive to a same column address strobe. In other examples, sub-arrays of a DRAM bank may be arranged such that input/output (IO) bits may be routed in a serialized manner over an IO wire. For these other examples, the IO wire may pass through a DRAM die including the DRAM bank and/or may couple to a memory channel or bus outside of the DRAM die. Other examples are described and claimed.

  • Patent number: 8941650
    Abstract: A CAD system enables a designer to freely modify a model of a design without regenerating a history of the model, as in traditional parametric feature based modeling. The CAD system automatically determines whether the modifications to the model invalidate current features associated with the model and whether the modifications create new features that should be added to the model. Such a CAD system enables a designer to quickly edit designs and simultaneously preserve design intent without requiring the significant computational resources of historical based approaches that regenerate a geometry upon every edit made by a designer.
