    • A memory array architecture employs a full Vdd bitline precharged voltage and a low wordline boost voltage, which is less than Vdd plus the threshold voltage of the access transistor. In a write mode, a first low level of a data bit is almost fully written to a storage element, however a second high level of the data bit is not fully written to the storage element. In a read mode, the first low level of the data bit is fully read out from the storage element, however the second high level of the data bit is not read out by utilizing the access transistor threshold voltage. This allows a sensing signal only with the first voltage level transfer to the Vdd precharged BL. A reference WL is preferably used for generating a reference bitline voltage for a differential Vdd sensing scheme. Alternatively, a single BL digital sensing scheme may be used. Lowering the wordline voltage results in a reduction in power consumption by saving power on Vpp generator and support circuits, and a reduction in the size of the Vpp generator and support circuits, and also eliminates high Vpp voltage related problems such as dielectric breakdown and other reliability concerns while avoiding a complex decoding scheme and saving cost.
    • 存储器阵列架构采用全Vdd位线预充电电压和低字线升压电压,其小于Vdd加上存取晶体管的阈值电压。 在写入模式中,数据位的第一低电平几乎完全写入存储元件,然而数据位的第二高电平未完全写入存储元件。 在读取模式下,数据位的第一低电平从存储元件完全读出,然而数据位的第二高电平不通过利用存取晶体管阈值电压被读出。 这允许感测信号仅在第一电压电平传输到Vdd预充电BL。 参考WL优选地用于产生用于差分Vdd感测方案的参考位线电压。 或者,可以使用单个BL数字感测方案。 降低字线电压通过节省Vpp发生器和支持电路上的功率以及减小Vpp发生器和支持电路的尺寸而降低功耗,并且消除了与Vpp电压相关的高电压问题,例如介质击穿和其他可靠性 同时避免复杂的解码方案并节省成本。

    • A short cycle DRAM use a floating wordline, dynamic row decoder and bitline VDD precharge, which improves the array efficiency of the short cycle DRAM (3-6 ns) without compromising its performance. A small size wordline driver circuit is provided to reduce the row size of the short cycle DRAM without compromising row access timing. A dynamic decoding operation is implemented which intentionally allows some of the deselected wordlines to float during row access. A Vdd bitline precharge/sensing technique avoids a detrimental (or positive) coupling effect to the floating wordlines during row accessing. A Vdd data-line (or DQ) precharge for a read operation, and control of incoming data timing avoids a detrimental (or positive) coupling effect for a write operation.
    • 短周期DRAM使用浮动字线,动态行解码器和位线VDD预充电,这提高了短周期DRAM(3-6ns)的阵列效率,而不损害其性能。 提供了一种小尺寸字线驱动器电路,以减少短周期DRAM的行大小,而不会影响行访问时序。 实现动态解码操作,其有意地允许一些未选择的字线在行访问期间浮动。 Vdd位线预充电/感测技术在行访问期间避免了对浮动字线的有害(或正)耦合效应。 用于读取操作的Vdd数据线(或DQ)预充电以及输入数据时序的控制避免了写入操作的有害(或正)耦合效应。
