Claims25
A semiconductor memory circuit comprising:
- at least one electrical line;
- and
- at least one keeper circuit electrically connected to the at least one electrical line, the keeper circuit including a first transistor, a terminal of the first transistor is driven by a dedicated control signal, wherein the dedicated control signal is configured to keep the voltage of the at least one electrical line at a first voltage.
A method for stabilizing voltage on a target line in a memory circuit, comprising:
- electrically coupling the target line to a source having a first voltage via a transistor having a gate, the gate having a threshold voltage,
- charging the target line to a second voltage,
- selectively generating a dedicated signal exceeding the threshold voltage, and applying the signal to the gate to operate the transistor in accordance with the signal, wherein, the voltage on the target line is maintained at the first voltage via a connection of the target line to the source while the signal is applied.
A semiconductor memory circuit comprising:
- at least one electrical line;
- and
- at least one keeper circuit electrically connected to the at least one electrical line, the keeper circuit including a first transistor having a gate, the gate being not electrically connected to the at least one electrical line, and the gate being controlled to keep the voltage of the at least one electrical line at a first voltage.
