摘要： A system and method is disclosed for writing early within a memory cycle by injecting a small voltage difference signal prior to setting a sense amplifier, and thereafter setting the sense amplifier which amplifies the small voltage signal to predetermined high and low voltage logic levels for writing to the memory cell. In this way, writing can complete in about the same time as reading, without risking corruption of data on adjacent bitlines in the memory. Local bitswitches apply first and second write voltages having a small voltage difference to a true bitline and a reference bitline prior to setting the sense amplifier.

摘要： A system and method is disclosed for writing early within a memory cycle by holding only one of a true bitline and a reference bitline at a fixed potential, e.g. ground, when the sense amplifier is set. The sense amplifier amplifies a small voltage difference between the true bitline and the reference bitline to predetermined high and low voltage logic levels to write a datum to the memory cell. In this way, writing can complete in about the same time as reading, without risking corruption of data on adjacent bitlines in the memory. The bitlines are precharged to a fixed potential in a conduction path through the bitswitches, rather than using local precharge devices at the sense amplifier. To write, bitswitches and write path transistors apply the fixed potential to one of the true bitline and the reference bitline. Bitswitches on such other memory cells not currently being written isolate the bitline pairs coupled to those memory cells when setting the sense amplifiers, such that the stored contents of such memory cells not being written are refreshed (written back) at the time that the selected memory cell is written.
摘要翻译：公开了一种系统和方法，用于通过仅保持固定电位的真正位线和参考位线中的一个，例如在存储器周期内早期写入。当感测放大器被设置时。读出放大器将真实位线和参考位线之间的小电压差放大到预定的高电压和低电压逻辑电平以将数据写入存储器单元。以这种方式，写入可以在读取的同一时间内完成，而不会在存储器中的相邻位线上的数据损坏风险。位线通过位开关预先充电到导通路径中的固定电位，而不是在读出放大器处使用局部预充电器件。要写入，位开关和写入通道晶体管将固定电位施加到真正的位线和参考位线之一。当设置感测放大器时，当前未被写入的其他存储器单元上的开关将隔开存储单元耦合的位线对，使得在所选择的存储器时刷新（回写）未被写入的存储单元的存储内容单元格是写的。

摘要： An approach for providing fine granularity power gating of a memory array is described. In one embodiment, power supply lines are disposed in a horizontal dimension of the memory array parallel to the word lines that access cells arranged in rows and columns of the array, wherein each of the supply lines are shared by adjacent cells in the memory. Power supply lines that activate a row selected by one of the word lines are supplied a full-power voltage value and power supply lines that activate rows adjacent to the selected row are supplied a half-power voltage value, while the power supply lines of the remaining rows in the memory array are supplied a power-gated voltage value.

摘要： Methods of setting wordline up-level voltage in as-fabricated SRAM. In one example, the method includes determining the relative speed, or strength, of 1) the combination of the pass-gate and pull-down devices and 2) the pull-up devices in the bitcells of the SRAM. These relative strengths are then used to adjust the wordline up-level voltage, if needed, to decrease the likelihood of the SRAM experiencing a stability failure. Corresponding systems are provided for determining the relative strengths of the devices of interest, for determining the amount of up-level voltage adjustment needed, and for selecting and setting the up-level voltage.
