摘要： An apparatus, a method, and a computer program are provided to efficiently use a microprocessor array. Typically, microprocessor arrays can be divided into multiple subarrays. Also, in the conventional arrays, each of the subarrays were engaged when the microprocessor array is used. To alleviate the power consumed by the microprocessor arrays, row selection logic is employed to engage only specific rows of subarrays. Therefore, power consumed by unused subarrys is saved.

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.

摘要： Systems and methods for decreasing the sensitivity of a sense amplifier to variations in the threshold voltages of the data line pull-down transistors by pre-charging the intermediate nodes of the sense amplifier to the voltages on the opposing bit lines when the sense amplifier is not enabled. In one embodiment, the intermediate nodes are coupled to the input bit lines through transistors that are switched on when the sense amplifier is not enabled and switched off when the sense amplifier is enabled. In one embodiment, the intermediate nodes are pre-charged to a predetermined voltage before being pre-charged to the voltages on the bit lines. In one embodiment, the bodies of the data line pull-down transistors may also be body-tied to the opposing intermediate nodes to increase current flow through these transistors, particularly on the side of the sense amplifier that will be pulled low when the sense amplifier is enabled.

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 pre-charging opposing nodes in a sense amplifier to substantially the same voltage in order to reduce or eliminate malfunctions arising from differences in threshold voltages of transistors coupled to the opposing nodes. 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. In one embodiment, the intermediate nodes are pre-charged by coupling them to a voltage source through pre-charge paths that do not include the data line pull-down transistors. In one embodiment, the method also includes decoupling the pre-charge paths after pre-charging the intermediate nodes and then enabling the sense amplifier.

摘要： A memory system including a memory array with redundant wordlines. The memory system includes a memory wordline tester that determines if any of the wordlines exhibits a defect. The memory system also includes decoder redundancy logic that efficiently couples to wordline shift logic using a reduced number of control signal lines therebetween. The shift logic shifts defective wordlines to upstream wordlines in the array to bypass the defective wordlines.
