摘要： 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.

摘要： Disclosed is an apparatus for and a method of overcoming signal delay problems in a read-out path occurring in connection with pipelined memory circuits. A latch type sense amplifier (SA) is used to receive the memory cell logic levels during a pre-charge state in a cycle prior to read-out. Thus, the SA may quickly provide an output signal during a read latch clock cycle. The SA output is passed through a dynamically enabled logic circuit to a latch circuit for holding the receiving logic value for use in the next clock cycle.

摘要： A method, an apparatus, and a computer program are provided to reduce the number of required latches in a deep pipeline wordline (WL) decoder. Traditionally, a signal local clock buffer (LCB) has been responsible for providing a driving signal to a WL driver. However, with this configuration, a large number of latches are utilized. To reduce this latch usage, a number of LCBs are employed, such that one latch can enable an increased number of WLs. Hence, the overall area occupied by latches is reduced and power consumption is reduced.

摘要： Systems and methods for increasing the amount of current that can flow through the data line pull-down transistors in a sense amplifier by tying the bodies of these transistors to a voltage other than ground. In one embodiment, the bodies of the data line pull-down transistors in a sense amplifier are tied to the intermediate nodes on the opposing side of the sense amplifier to increase the current flow through the data line pull-down transistors, and also to reduce the voltage at the intermediate node that will be pulled low by the action of the bit line transistors. In one embodiment, the sense amplifier also includes pre-charge circuits which pre-charge the intermediate nodes to a predetermined voltage that is not reduced by the threshold voltage of the pull-down transistors.

One embodiment is a method including providing a silicon-on-insulator (SOI) sense amplifier having intermediate nodes between the transistors coupling each output data line to the corresponding input bit line and pre-charging each intermediate node to a predetermined voltage while the sense amplifier is not enabled.
