摘要： Isolation of faulty links in a transmission medium including a method that includes receiving an atomic data unit via a multi-link transmission medium that has a plurality of transmission links. An error condition is detected and it is determined that the error condition is isolated to a single transmission link. It is determined if the single transmission link has been isolated previously as a failing transmission link a specified number of times within an interval specified by a timer. If the single transmission link has been isolated previously as a failing transmission link a specified number of times within an interval specified by a timer then: identifying the single transmission link as a faulty transmission link; resetting the timer; and outputting an identifier of the single transmission link.

摘要： Failing bus lane detection using syndrome analysis, including a method for receiving a plurality of syndromes of an error detection code, the error detection code associated with a plurality of frames that have been transmitted on a bus that includes a plurality of lanes and is protected by the error detection code. The method includes performing for each of the lanes in each of the syndromes: decoding the syndrome under an assumption that the lane is a failing lane, the decoding outputting a decode result; determining if the decode result is a valid decode; and voting for the lane in response to determining that the decode result is a valid decode. A failing lane is then identified in response to the voting, with the failing lane being characterized by having more votes than at least one other lane on the bus.

摘要： Performing wear-leveling and bad block management of limited lifetime memory devices. A method for performing wear-leveling in a memory includes receiving logical memory addresses and applying a randomizing function to the logical memory addresses to generate intermediate addresses within a range of intermediate addresses. The intermediate addresses are mapped into physical addresses of a memory using an algebraic mapping. The physical addresses are within a range of physical addresses that include at least one more location than the range of intermediate addresses. The physical addresses are output for use in accessing the memory. The mapping between the intermediate addresses and the physical addresses is periodically shifted. In addition, contents of bad blocks are replaced with redundantly encoded redirection addresses.

摘要： A method for receiving a data stream that includes data samples, each data sample having one of a plurality of actual values. For each data sample in the data stream, a first index in a dictionary is selected. The dictionary includes indices corresponding to each of the plurality of actual values. The first index corresponds to an actual value of the data sample. A predicted value of the data sample is generated in response to previously received data samples in the data stream and to a prediction algorithm. A second index in the dictionary that corresponds to an actual value in the dictionary that is closest to the value of the predicted value is selected. The difference between the first index and the second index is calculated and compressed. The compressed difference between the first index and the second index is then output. This process is performed for each data sample in the data stream.

摘要： A memory system that includes a plurality of memory arrays having memory cells characterized by a variable write time. The memory system also includes a memory bus configured to receive write commands, and a plurality of data buffers configured to communicate with the memory arrays. The memory system further includes an address buffer configured to communicate with the memory arrays to store the write addresses. A mechanism configured to receive a write command and to split a data line received with the write command into a number of parts is also included in the memory system. The parts of the data line are stored in different data buffers and the writing of the parts of the data line to memory arrays at the write address is initiated. The write command is completed when write completion signals specifying the write address have been received from all of the memory arrays.

摘要： Selecting bins in a memory by receiving a target cost for performing writes at an analog memory that is capable of storing a range of values. Possible bins that may be created in the range of values and a cost associated with each possible bin are determined. Each possible bin includes one or more of the values. A group of bins are identified, the group of bins are among the possible bins with associated costs that are within a threshold of the target cost. A maximum number of bins are selected from the group of bins that have non-overlapping values. The selected bins are stored along with the values of the selected bins utilized to encode and decode contents of the analog memory.

摘要： An analog memory having adjustable write bins including a system for writing to the memory. The system includes a write apparatus interpreting one or more write control signals, generating a write signal, and applying the write signal at a selected memory location to store a desired content. The selected memory location is subject to data dependent noise and is capable of storing a range of values grouped into “n” bins configured such that the average cost to write to at least “n-1” of the bins is within a threshold of a target cost for the selected analog memory location. The system also includes a read apparatus. The system further includes write control circuitry that includes a write signal selector selecting the one or more write control signals responsive to the desired content, current content of the selected memory location, and a bin associated with the desired content.
