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 memory element includes a memory which is operable according to operating parameters from at least two sets of operating parameter values and an operating parameter control which is implemented to receive operating state information and to select a set of operating parameter values for the operation of the memory based on the operating state information.
摘要:
Methods and apparatus for storing data in different regions of the memory device based on, for example, a reliability requirement of the data. A memory controller may determine a category for data, for example, high reliability data and low reliability data, prior to storing the data in memory. The data may be stored in a region of memory associated with the category of data according to a method associated with the category of data. For example, high reliability data may be stored in a particular region of memory using lower clock frequencies, with additional error correction bits, and/or at multiple redundant locations. In contrast, low reliability data may be stored other regions of the memory using higher clock frequencies, without additional error correction bits and/or at singular locations (i.e., without redundant locations.
