摘要:
A system and method utilize a memory device that may be accessed by a plurality of controllers or processor cores via respective ports of the memory device. Each controller may be coupled to a respective port of the memory device via a data bus. Each port of the memory device may be associated with a predefined section of memory, thereby giving each controller access to a distinct section of memory without interference from other controllers. A common command/address bus may couple the plurality of controllers to the memory device. Each controller may assert an active signal on a memory access control bus to gain access to the command/address bus to initiate a memory access. In some embodiments, a plurality of memory devices may be arranged in a memory package in a stacked die memory configuration.

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.

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.

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.
