    摘要: In some examples, a memory device has a memory array configured to include sets of bit cells grouped based in part on an arrangement of local source lines. Each of the groups of cells may include an assist bit having a lower impedance than the other bit cells of the group to cause current distributed by the local source lines to be largely provided to the assist bit. In some examples, the assist bit include a shorted tunnel junction and in other examples, multiple assist bits may be connected by one or more bridge assisted bit lines.

    摘要: A circuit in dynamic random access memory devices includes a command extension circuit. The command extension circuit is configured to generate at least one multiple-cycle command signal by lengthening a single-cycle clock command signal from a command decoding circuit. Control logic extends and reduces the multiple-cycle command signal to provide additional functions such as burst length and burst chop. Additional control logic is configured to determine whether a clock signal is enabled in output control logic circuitry according to the multiple-cycle command and logic level generated in the output logic circuitry.

    摘要: Methods and circuits detect a burst error in a block of data bits. Coset calculator circuits calculate coset leaders from a syndrome generated from the data bits of the block. The coset calculator circuits calculate the coset leaders for each frame of the data bits. For each frame, comparator circuits input a corresponding coset leader of the coset leaders. Each comparator circuit determines, for each burst-length portion of one or more burst-length portions within the corresponding coset leader, whether the coset bits of the corresponding coset leader are zero except for the coset bits within the burst-length portion. An error-locator circuit outputs an error vector describing the burst error in the block in response to one of the comparator circuits determining that the coset bits of the corresponding coset leader are zero except for the coset bits within one of the burst-length portions within the corresponding coset leader.
