    摘要: A memory device for efficient word line, bit line and precharge tracking is provided. The memory device includes a memory array, one or more address decoders, a word line driver, a plurality of sense amplifiers, a reference word line column, a reference bit line column, and a control circuit. The control circuit generates a control signal to perform read and write operations on the memory device. The address decoder selects a bit line and a word line. The selected word line is activated by the word line driver. While the reference word line column is used for vertical tracking of the word line, the reference bit line column is used for vertical tracking of the bit line. The sense amplifiers are activated to read the bit line.

    摘要: A technique for reducing the bitline leakage current while maintaining a level of performance characteristics of low threshold voltage transistors in deep submicron CMOS technology incorporates a reference voltage generator circuit in combination with bias transistor MBIAS. The output of a static logic gate is connected to the input terminal of the pull-down devices. The reduction in leakage current through pull-down devices whenever a read operation is not performed contributes to a significant reduction in overall leakage current in the circuit.

    摘要: A method supplies voltage to a bit line of a memory device. The method includes precharging, with a precharging device, the bit line to an output potential, deactivating the precharging device during a read action related to the bit line, reading, during the read action, an information via the bit line, and routing, during the read action, a virtual voltage supply line to a supply potential of the memory device to supply voltage to memory cells of the memory device assigned to the bit line. The precharging device of the bit line is activated/deactivated as a function of the potential of the virtual voltage supply line.
