    • A k-to-2k decoder is provided. Within the final stage of a k-to-2k decoder is a plurality of word line drivers. These word line drivers utilize clocking signals to fire word lines to a memory array. However, power consumption by clocks has become a serious issue with the increase component density on silicon wafers. To alleviate the problem, signals from the first stage of the k-to-2k decoder provide enablement signals to Local Clock Buffers (LCBs) that allow the word line drivers to fire. The enablement signal reduces the number of active buffers and signals carried to word line drivers, reducing power consumption.
    • 提供k-to-2k解码器。 在k-to-2k解码器的最后阶段是多个字线驱动器。 这些字线驱动器利用时钟信号将字线触发到存储器阵列。 然而,随着硅晶片的组件密度的增加,时钟功耗成为一个严重的问题。 为了减轻这个问题,来自k-2k解码器的第一级的信号向本地时钟缓冲器(LCB)提供允许字线驱动器触发的启动信号。 启用信号减少了向字线驱动器传送的有效缓冲器和信号的数量,从而降低了功耗。

    • A sum decoder is disclosed including multiple sum predecoders, a carry generator, and multiple rotate logic units. Each sum predecoder receives multiple bit pairs of non-overlapping segments of a first and second address signal, and produces an input signal dependent upon the bit pairs. The carry generator receives a lower-ordered portion of the first and second address signals, and generates multiple carry signals each corresponding to a different one of the sum predecoders. Each rotate logic unit receives the input signal produced by a corresponding sum predecoders and a corresponding one of the carry signals, rotates the bits of the input signal dependent upon the carry signal, and produces either the input signal or the rotated input signal as an output signal. A memory is described including the sum decoder, a final decode block, and a data array. The final decode block performs logical operations on the output signals of the sum decoder to produce selection signals. Each of the selection signals activates a word line of the data array. A method is disclosed for producing signals for accessing a memory. Highest ordered portions of the first and second address signals are divided into multiple non-overlapping segments. An input signal (i.e., an I term) is generated for each of the segments, as is a carry signal. For each of the segments, when the corresponding carry signal is set, the corresponding I term is rotated one bit position. The I terms are produced as the signals.
    • 公开了一种和解解码器,其包括多个和预测解码器,进位发生器和多个旋转逻辑单元。 每个和预解码器接收第一和第二地址信号的非重叠段的多个比特对,并且根据比特对产生输入信号。 进位发生器接收第一和第二地址信号的低阶部分,并且产生每个对应于预测解码器中的不同一个的多个进位信号。 每个旋转逻辑单元接收由相应的和预测码器和相应的一个进位信号产生的输入信号,根据进位信号旋转输入信号的位,并产生输入信号或旋转的输入信号作为输出 信号。 描述包括和解码器,最终解码块和数据阵列的存储器。 最终解码块对和解码器的输出信号执行逻辑运算以产生选择信号。 每个选择信号激活数据阵列的字线。 公开了一种用于产生访问存储器的信号的方法。 第一和第二地址信号的最高有序部分被分成多个非重叠段。 对于每个段产生输入信号(即I项),进位信号也是如此。 对于每个段,当相应的进位信号被设置时,对应的I项被旋转一位位置。 我的条款是作为信号产生的。
