    摘要: A double data rate interface in which the set-up interval is extended for a data path in which data is delayed relative to the other data path. Data is latched into a register comprised of mid cycle type latches, such as for example L2* latches. For example, if the delayed half of the data is not available until the second half of the double data rate cycle, the second half of the data is allowed to have a set-up interval around the mid cycle point while the on-chip timing logic launches the least delayed half of the data on the clock edge after it is set up, without waiting for the expiration of the set up interval of the delayed data.

    摘要: A system and method to organize and use data sent over a double data rate interface so that the system operation does not experience a time penalty. The first cycle of data is used independently of the second cycle so that latency is not jeopardized. There are many applications. In a preferred embodiment for an L2 cache, the system transmits congruence class data in the first half and can start to access the L2 cache directory with the congruence class data.

    摘要: A semiconductor memory circuit enabling replacement of defective memory elements and associated circuitry with non-defective spare elements of the RAM and associated circuitry, is scanned to enable replacement of a defective RAM element prior to repair of the RAM. A set of set/reset latches are coupled to receive the signal from the memory elements, and a multiplexer control circuit coupled to receive a shift signal and a ram_inhibit signal from a multiplexer to provide specific input signals to the multiplexer components. When a scan operation begins an active clock signal sets a set/reset latch to ram_inhibit mode and this blocks the memory elements from influencing the state of memory output latches, whereby when an memory operation begins, an active clocking signal will reset the set/reset latch into system mode to cause the multiplexers pass appropriate signals from the memory elements to the output latches, and the spare memory element is activated to replace a defective memory element.

    摘要: Data is protected during conversion from one or more source error correction codes to one or more destination error correction codes by generating check bits of the destination error correction codes prior to a detection for errors in the source error correction codes. After commencing generation of these check bits, a detection is made for any errors in the source error correction codes. These errors are subsequently corrected in the destination error correction codes by complementing the erroneous bits of the destination error correction code. In addition, various logic reduction techniques may also be implemented to increase efficiency.

    摘要: A technique for error detection is provided. A controller is configured to detect errors by using error correcting code (ECC), and a cache includes independent ECC words for storing data. The controller detects the errors in the ECC words for a wordline that is read. The controller detects a first error in a first ECC word on the wordline and a second error in a second ECC word on the wordline. The controller determines that the wordline is a failing wordline based on detecting the first error in the first ECC word and the second error in the second ECC word.

    摘要: Methods of error correction code (ECC) debugging may comprise detecting whether a bit error has occurred; determining which bit or bits were in error; and using the bit error information for debug. The method may further comprise comparing ECC syndromes against one or more ECC syndrome patterns. The method may allow for accumulating bit error information, comparing error bit failures against a pattern, trapping data, counting errors, determining pick/drop information, or stopping the machine for debug.

    摘要: Correcting memory device (chip) and memory channel failures in the presence of known memory device failures. A memory channel failure is located and corrected, or alternatively up to c chip failures are corrected and up to d chip failures are detected in the presence of up to u chips that are marked as suspect. A first stage of decoding is performed that results in recovering an estimate of correctable errors affecting the data or in declaring an uncorrectable error state. When an uncorrectable error state is declared, a second stage of decoding is performed to attempt to correct u erasures and a channel error in M iterations where the channel location is changed in each iteration. A correctable error is declared in response to exactly one of the M iterations being successful.
