    摘要: Systems, devices and methods are disclosed. In an embodiment of one such device, an embodiment of a memory device includes a command decoder that is operable to decode received write enable, row address strobe and column address strobe signals to place the memory device in at least one reduced power state despite the absence of either a clock enable signal or a chip select signal. The command decoder performs this function by decoding the write enable, row address strobe and column address strobe signals in combination with at least one address signal received by the memory device. The command decoder can also decode a no operation command, which differs from the at least one reduced power state by only the state of the write enable signal. As a result, when the at least one reduced power state is terminated by a transition of the write enable signal, the memory device automatically transitions to a no operation mode.

    摘要: A device includes a pattern-recognition processor. The pattern recognition processor includes blocks, such that each of the blocks include a plurality of feature cells configured to analyze at least a portion of data to be analyzed and to selectively provide a result of the analysis. The pattern recognition processor also includes block deactivation logic configured to dynamically power-down the block.

    摘要: Multi-port memory having an additional control bus for passing commands between ports have individual ports that can be configured to respond to a command received from an external control bus or to a command received from the additional control bus. This facilitates various combinations of ports to vary the bandwidth or latency of the memory to facilitate tailoring performance characteristics to differing applications.

    摘要: A DRAM device includes an ECC generator/checker that generates ECC syndromes corresponding to items of data stored in the DRAM device. The DRAM device also includes an ECC controller that causes the ECC syndromes to be stored in the DRAM device. The ECC controller also causes a flag bit having a first value to be stored in the DRAM device when a corresponding ECC syndrome is stored. The ECC controller changes the flag bit to a second value whenever the corresponding data bits are modified, this indicating that the stored syndrome no longer corresponds to the stored data. In such case, the ECC controller causes a new ECC syndrome to be generated and stored, and the corresponding flag bit is reset to the first value. The flag bits may be checked in this manner during a reduced power refresh to ensure that the stored syndromes correspond to the stored data.

    摘要: A DRAM memory device includes several banks of memory cells each of which are divided into first and second sets of memory cells. The memory cells in the first set can be refreshed at a relatively slow rate to reduce the power consumed by the DRAM device. Error checking and correcting circuitry in the DRAM device corrects any data retention errors in the first set of memory cells caused by the relatively slow refresh rate. The memory cells in the second set are refreshed at a normal rate, which is fast enough that data retention errors do not occur. A mode register in the DRAM device may be programmed to select the size of the second set of memory cells.
