    摘要: 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.

    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.
