摘要:
The invention relates to a method, to a first and a second device (1, 2) and to a system (10) comprising the first and second device (1, 2) for transferring data, said system and devices matching the user data transfer rate during the data transfer between the first and the second device (1, 2). The first device (1) comprises in particular a medium access controller and operates in the second layer according to the OSI reference model, whilst the second device (2) transmits and receives user data in the first layer according to the OSI reference model and comprises an interface unit (24) for a DSL connection. The transfer rate match is achieved in particular by PAUSE frames according to the IEEE 802.3-2004 standard and the second device also operates in the second layer according to the OSI reference model to transmit and receive the PAUSE frames.

A memory circuit comprises a D/A converter connected with an input/output circuit and with a writing circuit, wherein the D/A converter converts a digital data with at least two digital bits received from the input/output circuit to one analog value and forwards the analog value to the writing circuit, wherein the digital data is at least a part of a floating point number, wherein the writing circuit writes the analog value in at least one selected memory cell, and an A/D converter connected with a reading circuit and with the input/output circuit, wherein the reading circuit reads an analog value from a selected memory cell and forwards the analog value to the A/D converter, wherein the A/D converter converts the analog value to digital data, and wherein the A/D converter forwards the digital data to the input/output circuit. Furthermore, a method is provided for reading data from at least one memory cell of a memory, wherein an analog value is read from the memory cell and the analog value is corrected according to a correction factor representing a storage time the analog value was stored and wherein the corrected analog value is converted to digital data.

A display having a screen, and memory for storing picture data is disclosed. In one embodiment, the screen includes a plurality of pixels, the pixels in a first mode of the display being controlled by the picture data stored in the memory, and in a second mode of the display being controlled by picture data received from an external processing unit.
摘要:
A method of adjusting an interface voltage includes transferring data between a memory device and a controller, and detecting whether an error occurred in the transfer of data. An interface voltage of at least one of the memory device and the controller is adjusted based on the detection.
摘要:
Method of controlling a driver strength and a termination impedance of a signal line of an interface, wherein the driver sends an output signal as an alternating voltage with a frequency, wherein the signal line is terminated with a termination impedance, wherein the driver strength is changed depending on a changing of the frequency of the output signal.
摘要:
A method and apparatus for accessing a memory device. The method includes providing control signals for an access command to the memory device via an asynchronous interface and transmitting data for the access command to the memory device. The method also includes encoding, into the transmitted data, a clock signal. The encoded clock signal in the transmitted data is used by the memory device for receiving the data transmission.
摘要:
Method and apparatus for refreshing selective memory cells. A refresh circuit is connected with the memory cells and operates to refresh data stored in the memory cells on the basis of the values of valid bits having a predefined association with the memory cells.
摘要:
A method of sending data on request from a memory to a device, wherein the memory receives a request from the device for sending predetermined data to the device, wherein the memory sends data and information about the data to the device.
摘要:
A method receives data including synchronization information. The method includes obtaining a synchronization for receiving the data based on the synchronization information. The method includes generating, during receiving of the data, maintenance information indicative of whether the synchronization is being maintained based on the synchronization information. The method includes continuing, upon loss of the synchronization, to generate the maintenance information based on the synchronization.
