  • Patent number: 7305525
    Abstract: A memory system for network broadcasting applications, such as video/audio applications, has at least one memory which is divided into a plurality of addressable memory units, which have a respective dedicated output for interchanging data. The inputs of a matrix switch are connected to a respective output of a different memory unit. The matrix switch is operated such that a plurality of the memory units are connected to its output in a sequential order. A first sequence of memory units and a second sequence of memory units are connected to its output independently. This results in a memory system, which can handle a number of requests to the same memory at staggered times. The interaction of the individual memory units with the matrix switch allows a high data throughput and a short access time.

  • Patent number: 6829554
    Abstract: A method for classifying semiconductor components by their performance characteristics includes reading an identifier associated with a component and storing, in conjunction with the identifier, first and second performances values for that component. These performance values represent the component's achieved operating speed at each of two different temperatures. The component is then allocated to a speed category on the basis of the first and second performance values.

  • Patent number: 6590824
    Abstract: A dynamic semiconductor memory and a method for operating such a memory includes memory banks with memory cells disposed in rows, and registers associated with the memory banks for storing an address of an open, activated word line. In the event of an external refresh command, a control device causes, after the refresh operation, the state of the memory banks to be reestablished, in particular, the word line whose address was stored in the register to be reactivated. Such a purely on-chip measure increases the operating speed of the memory.
