摘要： An embedded memory system that includes DRAM cells and logic transistors. The capacitor of the embedded memory responds to a positive bias voltage of ½ Vdd. The wordline driver of a p-channel access transistor applying the positive power supply voltage when the p-channel access FET is not being accessed and a voltage lower than the threshold voltage of the p-channel access FET is being accessed. For DRAM cells containing an n-channel access FET, the wordline driver applies either a negative voltage or the ground voltage to the n-channel access FET when the DRAM cell is not being accessed. A second voltage composed of Vdd and a boosted voltage is applied to the n-channel FET when the DRAM cell is being accessed.

摘要： The row decoder includes an internal node and an output node. A decoding unit receives a plurality of externally-applied address signals and pulls down the internal node to a logic low voltage when the plurality of address signals have an active state. A latch unit pulls up the output node to a logic high voltage in response to the pulling-down of the internal node by the decoding unit, pulls down the output node to the logic low voltage when the internal node is at the logic high voltage, and reduces a voltage at the internal node to a voltage less than the logic high voltage and greater than the logic low voltage based on a selection signal.
