  • Patent number: 7536528
    Abstract: A memory arrangement includes an interface configured to transmit, code and/or decode data in the form of data packets in accordance with a predefined protocol. The memory arrangement includes at least two memory banks, each memory bank including at least one memory cell. The memory arrangement includes at least two memory-bank access devices configured to facilitate accessing the data of the at least one memory cell of each of the at least two memory banks. The memory arrangement includes at least two temporary storage devices configured to temporarily store data being transmitted between the interface and the at least two memory-bank access devices. Each of the at least two temporary storage devices is connected to the interface and to one of the at least two memory-bank access devices.

  • Patent number: 7515075
    Abstract: A circuit includes a data conversion circuit including a first input configured to receive a first serial data stream, a second input configured to receive a second serial data stream, and a third input configured to receive a third serial data stream. A first sampling circuit is coupled to the first, second, and third inputs and is configured to sample the first to third data streams based on a plurality of clock signals and to generate a corresponding plurality of first sampled signals. A second sampling circuit is configured to sample the plurality of first sampled signals based on a further clock signal. The further clock signal has a clock frequency different from a clock frequency underlying the first to third serial data streams.

  • Publication number: 20080055126
    Abstract: A device configured to parallelize N serial digital input signals includes at least M bit storage devices configured to each respectively store one bit of the N serial digital input signals and provide the one stored bit as a bit of a parallel digital output signal with a bit width M. M is greater than N and N is greater than 1. Symbols with a bit width M are transmitted via the N serial digital input signals such that each of the N serial digital input signals transmits a fraction of the respective symbol. A control device is configured to drive the plurality of bit storage devices cyclically such that at least M bits of the serial digital input signals, which belong to one symbol, are stored in the bit storage devices within a cycle.

  • Publication number: 20080028148
    Abstract: An integrated memory device includes a memory core having a plurality of memory cells and a group of terminals for communication between the memory device and an external electronic device. A data buffer temporarily stores data. The data buffer is coupled to the group of terminals and to the memory core. The data buffer includes a plurality of data buffer sections. Each data buffer section is capable of temporarily storing at least one data frame and being accessible by a respective data buffer address. A data buffer control unit is also provided.
